Presidency of Andrew Jackson Essay Example for Free

Presidency of Andrew Jackson Essay The early nineteenth century was first of all marked with the making of American national identity. Presidency of Andrew Jackson is usually addressed as revolution in American democracy as since that time rapid development of politics, social relationships, national economy and religious started. Tremendous social changes described in Tocqueville’s â€Å"Democracy In America† written in the middle of nineteenth century that amazed Europeans with tremendous democratic, social, national and economic development of the United States serves one more incontestable prove for the forming of American nation during the period. Jackson appeared a symbol of the self-made man for many Americans. He managed to inspire people the idea of American national identity through his multiple successful reforms and personal achievements 1. Strengthening of American political and party system, gradual development of two-party system, fair people-centered politics and successful innovations helped the nation to overcome previous colonial mentality and build a prosperous welfare society of XIX century America. Symbolizing himself the changes in country’s political system Jackson indeed made the nation to believe in him and his policy targeted to improve the lives of all common Americans. For many Americans who associated Jackson primarily with the Battle of New Orleans in 1912 his coming to power was a synonym of the same successes in archaic and corrupted political sphere . As the war hero Jackson captured imagination of people and dedicated loyalty of a great part of American society. He was believed to be a symbol, a kind of a national ideal, a self-made man possessing strong will and moral courage. Many researchers believe that the very idea of national identity, American nationalism has its roots in Jackson’s presidency 4. Jackson was elected a President of the United States in 1828, and soon supported several very important changes both in political and social milieus. Before all, Jackson increased the power of the Executive Office. This measure was targeted to ensure the rights of the common Americans and suggest them the idea of a sole nation. Jackson’s changes were first of all targeted to reinforce people, inspire them a vaporized feeling that a government is before all for the people, not vice versa. Jackson believed that no social group or privileged class are entitled to any special political or economic advantage. These rich minorities that were in power prior to Jackson didn’t respect the will of common Americans and the real political power was concentrated in the hands of an elite minority. Jackson’s electoral campaign and future policy was targeted to clean up corruption in Washington. In his electoral program Jackson declared that people were cheated by previous Adams’ administration and corruptions and intrigues in Washington defeated the will of common Americans. These ideas united people around the idea of fair politics: factory workers, frontiersmen, farmers, bankers, and businessmen from all across the United States rallied behind Jackson. He appeared that charismatic leader that gathered the nation. Even his nickname â€Å"King Andrew† serves a good illustration of his respect amidst the common people. These promises and real deeds of Jackson indeed helped people to identify them as Americans and became proud of the own country. Almost 20. 000 citizens, an incredible crowd in XIX century, greeted Jackson near the White House after he was elected! After Jackson was elected a president his primary efforts were focused on making that political and economic changes that eventually helped American society to become more democratic and welfare. Jackson sufficiently reconsidered the very idea of presidency, partially, the issue of presidential veto. Jackson changed the perception of the presidential veto. It had originally been viewed as something the president could do if he considered a bill unconstitutional. Jackson eventually made it clear that the president could veto a bill on whatever grounds he saw fit. The first president to proclaim himself the elected representative of all the American people, Jackson did not hesitate to use the power of veto. Jackson himself vetoed twelve bills, more than all of his predecessors all together. His use of the powers of removal and of executive orders paved the way for the modern American presidency 6. Jackson has made a government more open to the common people and sensitive to their wills through implementation of his principle of â€Å"rotation in office†. He believed that no person should regard officeholding as a right he decided to protect the nation from a permanent, aristocratic officeholding elite through removing of long-term officeholders. Nevertheless that only a small part of federal officials were indeed removed by Jackson, this policy helped the President to become even more popular in the society. This measure also helped Americans to trust authorities and respect political power 7. Rapid economic development and growing demand for man power determined rapid social migration within the county that also prompted self-identification of people. It was the very beginning of a legendary â€Å"American Dream† idea further united the nation. The old way of living was reshaped by the influence of Industrial Revolution. Traditional political system was unable to promote development of the country as far as both the political and economic layers concentrated in the hands of a small minority. Jackson, instead, suggested different standards of economic development. Jackson’s economic policy caused rapid development of territories, huge growth of cities and transportations. In the new democratic American society built by Jackson, people no longer associated themselves with family background, occupation, or class to define themselves. Believe in a self-made man based on the example of Andrew Jackson helped to new model of people’s self-identification according to the different standards 8. Jackson himself supported several controversial decisions that, however, were popular in that time society. One of such measures undertaken by Jackson was a notorious Indian Removal. National interest in Middle West territories and personal feelings of a President as a former Indian fighter led to the governmental decision to move all eastern Indian tribes to the territories beyond Mississippi. The removal policy of Jackson was popular among white majority of the country that obtained new fertile lands 9. Andrew Jackson’s foreign policy also promoted nation’s consolidation and evoked people’s proud of being Americans. The President eventually ended the long-lasting disputes with the United Kingdom and France. In 1937 Jackson recognized Texas’ independence from Mexico. At the same time he rejected the calls for its joining the country due to the slavery policy of the state. Territorial expansions of America were also helpful in forming of national dignity and proud of the common people. Jackson’s presidency, his political and social outlooks and reforms indeed help the nation to recognize its unity and role in establishment of fair democratic society. The rise of national identity during Jackson’s presidency helped people to build completely different nation and welfare country.

Goodbye Chicken Little :: essays research papers

The name of my book is Good-bye, Chicken Little, and was written by Betsy Byars. Betsy Byars has written over fifty books for young people. Her first book was published in 1962 and since then she has published regularly. She also won the Newbery Medal in 1971 and the American Book Award in 1981. Good-bye, Chicken Little is a book written for younger readers which I consider to be an adventurous book.   Ã‚  Ã‚  Ã‚  Ã‚  Good-bye, Chicken Little takes place in Morgantown, West Virginia. The story is written from a modern-day viewpoint. Jimmie Little, the main character, is a typical young boy who enjoys spending time with his friend Conrad. Mrs. Little, Jimmies mom, is a widow woman who has two children, Jimmie and Cassie. Both of these characters are very effective characters all throughout the novel. Jimmie and Mrs. Little are both very likeable characters.   Ã‚  Ã‚  Ã‚  Ã‚  Jimmie Little is scard of life. Ever since his father’s death, the world has seemed so unpredictable that Jimmie nicknamed himself Chicken Little. Good-bye, Chicken Little is a perceptive exploration of Jimmies reaction to his Uncle Pete’s death, which takes place at the beginning of the novel. Jimmies uncle is well known for his jokes and pranks. On a cold wintry day, while visiting the bar, Pete, while drunk, was dared to walk across the river which ran through town. As usual, Pete accepted the dare and wasn’t fortunate enough to make it across without falling in and being killed. Because Jimmie was at the river side when Uncle Pete began to cross the river and did nothing more than he did to stop him he feels worse than ever. This terrible feeling of guilt Jimmie has last only until a special party with his relative which provides him with the understanding to face life no matter what happens instead of running away. The novel is fast-moving a nd does a good job of holding your attention until the end. The climax of the story is when Mrs. Little all the sudden decides to have a party which will bring together all of their family that is still living.

Focus On Learner Pronunciation Problems Essay

In Portuguese, R at the beginning of words, at the end of words, or before a consonant is pronounced like H. Many Brazilian students carry this habit into English words, pronouncing â€Å"restaurant† as â€Å"hestaurant† and â€Å"far† as â€Å"fah.† It’s especially common when the English word and the Portuguese word are similar, such as in â€Å"restaurant† and â€Å"regular.† SOLUTION: First, I have my students work on pronouncing the English R sound by itself. I demonstrate the correct mouth position and they imitate me. Then, we work on each word while exaggerating the R sound – so we say rrrrememberrrr, for example. Finally, we practice making that exaggerated R sound shorter and shorter until the student gets used to saying remember with an English R. It feels a little ridiculous, but it works! PROBLEM: Similar words Fortunately, Portuguese and English have a lot of true cognates – words that are similar in both languages, such as area, animal, culture, famous, music, romantic, hamburger, and sports. This makes it easier to remember the vocabulary – but more difficult to remember to pronounce the words â€Å"the English way.† SOLUTION: To show the difference in the sounds, I make comparisons with words that they already know and pronounce well in English – â€Å"The ‘a’ in animal is like the ‘a’ in and,† for example. I also draw attention to syllable stress – popular in English vs. popular in Portuguese. PROBLEM: Final consonants Portuguese doesn’t have letters like D, T, G, P, and K at the end of words, so it’s common for Brazilian students to accidentally add a little vowel sound at the end of English words – so big sounds like bigg-ee and stop becomes stopp-ee. One of the most famous is difficult turning into difficulty – which is also an English word, but the first is an adjective and the second is a noun. SOLUTION: I start with words ending in P because they’re the easiest to practice – we practice saying â€Å"stop,† â€Å"help,† and others, and I tell them to keep their lips together for a second at the end, then â€Å"release† them without making an extra sound. Then we move on to â€Å"rock,† â€Å"get,† â€Å"thing,† â€Å"good,† and so on, again, â€Å"holding† the final consonant for a moment before â€Å"releasing† it soundlessly.

Mobile ad hoc networks MANET - Free Essay Example

Sample details Pages: 12 Words: 3630 Downloads: 7 Date added: 2017/06/26 Category Statistics Essay Did you like this example? Abstract Mobile Ad Hoc Network (MANET) is a wireless network capable of autonomous operation. MANET routing has no fixed base station and hence nodes in the network are mobile and self configuring. A MANET is characterized by multi hop routing so that nodes are not connected to layer 2 but can communicate through layer 3 routing. Don’t waste time! Our writers will create an original "Mobile ad hoc networks MANET" essay for you Create order In MANET every node is a potential router and the topologies are dynamic due to node mobility. This paper presents a comprehensive study of four MANET routing protocols ADOV (Ad Hoc On demand Distance Vector), DSR (Dynamic Source Routing), OLSR (Optimized Link State Routing) and TORA (Temporally Ordered Routing Algorithm). For experimental purpose six scenarios have been considered. These 6 scenarios are generated with 3 different traffic parameters namely high resolution video, light HTTP and high FTP load. This traffic was passed individually on to each scenario on 2 different node setup (20, 100 nodes). Finally, graphical evaluation of each protocol was based on their performances which are calculated on the basis of performance metrics used which are End to end delay, Network load and Throughput. Chapter 1: Introduction This chapter demonstrates a brief overview of the project. Now days in our day to day life we see so many changes around the world accelerating with respect to technology. In this technical world Internet has brought revolution in communication media. Communication is said to the method of information exchange either between two people or between two end users (in terms of computers). Communication is said to be done when a file or a message is passed over the medium among two people. Here the usage of internet comes into existence. Internet can be used as shared medium for information interchange between users around the globe. This information can be of any type: Short Message Mail File transfers Video Audio etc When these types of information are passed among internet, it uses either the wired media (for connecting users locally) or wireless media (for connecting locally or globally). When this information exchange is done the packets carry that information through the protocols available for the respective media to deliver the packet to the destination. This is the process of information exchange. In this paper, similar work is experimented over MANET (Mobile Ad Hoc Networks) [chapter 2] for information exchange using four different protocols. This setup was done internally over a virtual setup of networks using OPNET modeller 14.5. So the investigation of protocols is done based on the performance of each protocol. In the scenarios, each protocol is passed with 3 different types of traffics namely: High FTP load, High Resolution Video and Light HTTP Browsing. This thesis concludes the performance of four routing protocols towards through the end. Keywords: MANET, AODV, OLSR, TORA, DSR, OPNET Modeler 14.5. 1.1 Organisation of Thesis: This thesis gives an overview of how the project is organised with respect to each chapter. The very first chapter is Introduction of the Thesis, which shows a project idea and the tasks to achieve the goals. Second chapter Literature Survey which contains the studies and work which has been done previously by other authors on the related topics with the parameters used by them for their work. The scenarios used for my work are related somewhere by overall different results are taken with different parameters used. Again the classification and the background work of MANETs are explained following the comparison of MANET routing protocols. The parameters and scenarios used for my work are explained briefly with the simulation setup in chapter 3, Implementation. The results of the simulations and experiments performed are explained in chapter 4, Performance Evaluation and Design. The results are taken graphically which helps in comparing the results for routing protocols against the pe rformance metrics used to investigate the performance. The graphs are explained briefly in chapter 4. The results gathered with the help of scenarios in chapter 3 are concluded with the future work on the routing protocols in chapter 5, Conclusion and Future Work. Finally the supported documents for the project which helped in making the simulation and project start up is kept in Appendix A. And finally chapter 6 shows all the sources and references used for the thesis to help in achieving all the supported information and work. 1.2 Objective of Work The main objective of this work is to study the different routing protocols, which are developed for Mobile Ad hoc networks (MANETs), and to compare the different routing protocols by using simulation tool OPNET Modeler 14.5. As a part of the work four major routing protocols OLSR, AODV, DSR and TORA have been selected and carried out the simulations for comparing the performance of these protocols. Three performance metrics delay; Network Load and Throughput are used to compare the performance of the routing protocols. Objective 1 To get a clear understanding and functioning of different routing protocols for Mobile Ad hoc networks. This objective could be achieved by reading and understanding the various papers available on routing protocols of Mobile Ad hoc networks. Objective 2 To do a literature survey of previous work done on MANET Routing Protocols so that something different and efficient simulation could be introduced. For this objective different articles and papers published has been studied thoroughly and analysed from websites, books and all relevant resources available. By going through literature survey on routing protocols, the desired simulation environment and setup have been introduced with different simulation parameters. Literature Survey is explained in chapter 2. Objective 3 Conducting an experiment and collecting the output data: This objective has been achieved by designing the appropriate networks with the appropriate simulation parameters and running a simulation for different protocols for different performance metrics. After conducting the simulation the output data have been collected graphically. The results are shown graphically and explained in the project in chapter 4. Objective 4 Analyzing the output data and ending up with summary and the conclusion: The results have been studied and explained in chapter 4. After studying the simulation results conclusion has been made with some future work which can be done further. Conclusion of the project and future work is explained in chapter 5. Chapter 2: Literature Survey 2.1 Introduction This chapter gives a brief introduction about the work done in previous related papers and reports related to this project. In addition, the introduction to the routing protocols and their classification with respect to routing is demonstrated. This chapter is a short review of the previous work done and the additional objectives regarding routing protocols. The four MANET routing protocols are selected to evaluate the performances; they are OLSR, AODV, DSR and TORA. The further implementations of these protocols are explained later in this thesis (Chapter 3). MANET is an infrastructure less network which provides the freedom to the nodes to be free to move anywhere in the network (Stefano Basagni, 2004). 2.2 Related Work on Routing Protocols: As we see from (Mahmoud), analysis of two reactive protocols DSR and TORA were done using OPNET Modeller. In their simulation scenario, they used 50 wireless devices in each scenario with constant traffic parameters and protocol specification settings. They have passed FTP traffic of 1000 bytes making it constant throughout the simulation. Evaluation of these protocols was done based on the performance metrics used which are: Delay, Data dropped, Throughput and media access delay. Their simulation results shows that DSR performance was better than TORA in terms of throughput as TORA produces less throughput due to additional overhead used for path creation and path maintenance. At the same time TORA minimizes communication overhead by localization which results in less delay when compared to DSR as there is no such mechanism in DSR. Similarly, from (Zukarnain, 2009) they have done evaluation of MANET routing protocol AODV in order to establish the connection between the nodes since the mobile node can change their topology frequently. So their study was carried on different mobile node movement pattern which are: Random Waypoint Mobility Model, Random Walk Mobility Model and Random Direction Mobility Model. In order to evaluate the performance of the protocol with these node movement patterns, performance metrics used were Routing overhead, Throughput and Packet delivery ratio. They used 2 simulation scenarios where in the first scenario comparison was made on different mobility model varying different number of nodes 5, 10, 15, 20, 25 with fixed speed of 15m/s and in other case comparison was made to evaluate the protocol on different mobility models with varying speeds 5, 10, 15, 20 m/s and 50 nodes as constant all through. They concluded that Random waypoint model is best for AODV compared to other mobility m odels as the protocol produces highest throughput than compared to others. Other related work from (Nyirenda, 2009) gives the similar working of MANET routing protocols AODV, OLSR, DSR and TORA on OPNET 14.5. Their work carried out for study the performance of the four protocols by different performance metrics which are: Network load, Packet delivery ratio, Packet end-to-end delay and Throughput. The simulation setup which was implemented on 6 different scenarios where the traffic passing on to the network was ranging from low to high network load, nodes changing from 5, 20, 50 and with speed ranging from 10 m/s to 28 m/s. Mobility model used in this was Random waypoint model for mobility pattern. They conclusions included in their work showed that OLSR performed better compared to the other protocols as it has a bad routing overhead and hence it is well suited for large and complex networks. So apart from routing overhead OLSR performed better but with routing overhead DSR is better. But when in small network AODV is much better compared to other protocol s. So finally, proactive protocols perform well in high capacity links whereas reactive protocols perform better in low capacity networks. From another paper (Maltz, 2001), we see that working on demand routing protocols in MANET was done where DSR protocol was compared to other on demand protocols like AODV, TORA and DSDV. Simulation setup carried is represented in tables below: With the above simulation setup the protocols were evaluated based on the performance metrics used which was Packet delivery ratio, Routing overhead, Path optimality and lower speed of nodes. The conclusions showed that DSR performed well when referred to packet loss rate and routing over head is concerned. Of all careful implementation done with all the above parameters tested on the experiment test beds DSR out performed in every case scenario used when compared all the other protocols used in this setup. 2.3 Background Work A network can be said as association of different systems or organizations where sharing the information can be done collectively. Whereas in computing terms it can be simply defined as a group of computers connected together logically to share information like printing, faxing, etc The network can be divided into 2 types based on their working behaviour. They are: Infrastructure network: These networks are used where the topology is said to be limited and there is a fixed point like base station (generally referred as router) to transmit signals and the end points which are connected to base station communicate with each other devices on the network switching from one base station to another. When a node moves out of range within its network, then it is said to be connected to another base station range where this process is referred as handoff. We can often see this type of mechanisms in infrastructure and fixed or wired networks. Infrastructure less network: These networks are a typical type of networks where there are no such fixed nodes or topologies on the network and the end pints or devices on the network are free to communicate with each other devices on the network as each device on the network behave themselves as routers and encourages communication process all over the network. By this we can say that wireless technology is a promising technology that can tolerate the information exchange worldwide. In the last decade we can also see the constant increase in the growth wireless technology issues, one of which being mobile devices such as laptops, cell phones, PDAs etc Ad hoc networks are also the part of this type of network. Mobile Ad hoc network is a new technology emerged with the hypothesis of wireless networks. These networks are very typical and do not use any fixed infrastructure for communication process. The nodes connected in these networks are wireless links which are mobile in nature and communicate with each other mobile node in the network with radio transmission and topology is said to establish by the intermediate nodes on the network which are helpful for communication process. As there are no fixed infrastructure and limited topology constraints the nodes on the network are free to join and leave the network and this is possible as the nodes on the network are mobile. Due to this random movement of the nodes in the network the topology of the network changes dynamically. Due to this change protocol must be able to acclimatize with these movements and are also responsible to maintain the routes of the information travelled without disturbing network connectivity. This concept of ad hoc network allows each node on its network to act like router, resulting in the flow of information exchange with multi hop routing. These types of networks are widely used in military and other rescue applications. (Saadawi, 2003) 2.4 Routing: Routing is the process of moving the data from one place of the network to another. The one end should be the source which intends to transfer the data to the destination (other end). The concept of routing has been there since 1970s but it has caught the move in 1980s. In 1970s networks were simple and today there are large scale networks in existence. To move the data from one host to another at least one router is required in the network. Router has all the information regarding hosts in the network and it can manipulate the best possible route as well. (Javvin, 2004) Routing takes place at Layer 3 in OSI 7 layer Model. Some of the protocols at layer 3 are IP and IS-IS. These protocols carry the data between source and destination along with their addresses in the data packet. Routing involves two basic activities; Path Determination and Switching. These two activities are capable to determine the optical routing path and to transfer the data packets through internetworking. This is called Switching. Switching can still be easy where as determining the reliable path is difficult. Path Determination: Routing make use of the different routing protocols to determine the best possible path to deliver the data. Routing protocols use the metric to calculate which the best possible path to accomplish the task is. The metric used could be path bandwidth, path length, delay etc. to determine the optimal path. To determine the path in the network, routing algorithms maintains the routing tables which are used to store the routing information about the network. Routers communicate with each other in order to maintain their routing tables which make communication easier and faster. Routing information can vary according to the routing algorithm used for the process. (Cisco, 2010) Switching: Apart from path determination, router shows one more activity; Packet Switching. Switching simply means forwarding the required data from one interface to the another in order to reach the destination. In this case, the data to be forwarded is packet. The next interface address is decided by using the destination address present in the packet. Though the nodes know the next hop address, they still need to know how to use it. So for that reason they use routing tables. The routing table throws the packet away when the destination is unknown. But when the destination is known routing table posses all the interface information forming the route to the destination. (2006) The next hop address could be another host or either it could be a router. According to ISO developed hierarchical terminology, the systems which have the capability to forward the data from the source to the destination are called Intermediate Systems (IS) and the systems which fails to do so are called as End systems (ES). When it is a router it follows the same procedure as this one, and if it is a host it simply forwards the packet. In packet switching, the Layer 3 address of the source and the destination remains the same to authenticate the original sender and the receiver. However the Layer 2 address (MAC) changes from router to router and from router to host which at last determines the destination host. (Cisco, 2010) 2.5 Ad hoc Networks An ad hoc network is a collection of many autonomous nodes connected together by radio waves and maintain the connectivity in decentralised manner. Wireless ad hoc networks are connected through wireless links so there is no need of any physical medium and hence contend of the medium is always there such as noise, interference and fading. On ad hoc networks each node functions as a node and a router itself. It simply means there is no need of an additional switch or a router to route the data and the control is given to the nodes themselves. (Yang Li, 2010) 2.6 Mobile Ad hoc Networks: A Mobile Ad hoc Network is an autonomous network formed by hundreds or thousands of nodes. These networks dont need any infrastructure as they can act as a node and router itself. They are free to move anywhere in the network and are connected through radio links. The only limitation with the MANETs is that they can communicate in a particular rage of the radio waves and outside the network they need some additional arrangements to communicate. To overcome this limitation the Intermediate Node or sometimes called as Relays are brought into picture. Intermediate nodes help in forwarding the packets to the destination. In MANET nodes are free to travel anywhere in the network, hence network topology cannot be fixed for such networks and it keeps changing depending on the current location of the nodes. (ANTDS, 2001) The fundamental differences between the wired networks and MANET are: Asymmetric Links Redundant Link Interference Dynamic Topology 2.7 Characteristics of MANETs There are several MANET routing protocols which should handle the several inherent characteristics of MANETs as follows as mentioned in (Subbarao)(Jain, 2005): Dynamic Topologies: Since the MANET is infrastructure less ad hoc networks, the nodes are free to move arbitrarily. The mobility of nodes may be random and so unpredictable. So the links between the nodes may be unidirectional or bidirectional at times. Bandwidth Constrained, Variable Capacity Wireless Links: Wireless links generally are bandwidth constrained. Since there is a lower capacity in wireless links as compared to the wired links, the traffic congestion is typical rather than different. Energy/Power Constrained Operation: Energy consumption is vital in MANETs as these nodes operate typically off power limited sources. Some or all nodes in MANETs rely on batteries. Limited Physical Security: Wireless networks like MANETs are more vulnerable with the security issues available with them. Issues like eavesdropping, jammer attack, spoofing and denial of service attacks must be carefully considered. 2.8 Need of MANET Routing Protocols A mobile ad hoc routing protocol is used to discover new routes and maintain the existing routes between the nodes in the network. MANET (Mobile Ad Hoc Network) is the collecting of mobile nodes which are present in random manner in the network has the capacity to communicate and exchange information effectively over the network by facilitating the intermediate nodes for their communication. The essential task of a MANET protocol is to create or discover the correct and efficient routes between the nodes so that information can be delivered accurately with respect to time. Route construction should be done with less overhead and minimal bandwidth consumption for effective communication. 2.9 Applications of MANETs Applications of MANETs can be used in many critical situations today and are increasing widely. There are many applications of MANETs today and some of them are mentioned here. An ideal application is for search and rescue operations. Such kind of operations is characterized by the networks without having an infrastructure present. One of the reasons for this may be because all of the equipment was destroyed or may be the region is too remote. Rescuer must be capable of communicating to use their energy fairly and also they must maintain the security. Carrying the equipments for communication that the rescuers are already using makes the job easier. The commercial application for MANETs includes computing everywhere which means the mobile devices are free to move anywhere in the network and yet it is possible to be in communication with the devices. The computers are allowed to forward the data to another computer or data networks may be extended far beyond the considered reach. Such networks may be more widely available and much easier in use. Another important application of MANETs is Sensor Networks. Sensor networks are composed of very large number of small sensors which are able to detect number of properties of the area, for example; temperature, pressure, toxins, pollutions etc. In this case, the capability of sensor network is much limited. So there is always need to forward data to the central computer and for this purpose they have to rely upon others in order to forward data to the central computer. The sensor networks individually are limited in their computing capabilities but together can be very effective and the key to future homeland security. But individual sensors because of their limited computing capabilities can prove prone to failure and loss. There are many other applications of MANETs like personal area networking where the communicating nodes may be mobile phones, laptops etc. Also this has a potential in military operations with the nodes of the network as soldiers, tanks and airplanes. Many more areas includes civilian environment to diverse taxi cab networks, conference rooms, boats and ships. (Bluetronix, 2006) 2.10 Classification of Routing Protocols According to (Jain, 2005), ad hoc routing protocols can be classified mainly into two categories: Table driven (proactive) Routing
