CSE, Bhagwant Institute of Technology, Muzaffarnagar, UP, India ABSTRACT In this paper we are presenting a routing protocol comparison for mobile Ad-Hoc Networks. So far, the protocols have been analyzed theoretically. Compares the result from these theoretical/qualitative analyses and shows what properties the protocols have and do not have. As it can be seen from Table, none of the protocols support power conservation or Quality of Service. This is however working in progress and will probably be added to the protocols. All protocols are distributed, thus none of the protocols is dependent on a centralized node and can therefore easily reconfigure in the event of topology changes. This paper compared seven routing protocols on the basis of four parameters like hello message requirement, update destination, routing strategy and method of communication. AODV and CBRP only uses broadcast hello message. DSDV, WRP and AODV uses distance vector routing strategy and DSR and CBRP uses source routing that uses the concept of route cache. DSDV, WRP and TORA broadcast the packets in the network. CBRP uses flooding of the packets and DSR unicast the packet to next neighbor. Keyword: - MANET, AODV, DSR, WRP and TORA etc. 1. INTRODUCTION A Mobile Ad hoc Network (MANET) is a collection of mobile platforms that form a dynamic infrastructure-less communication network wherever it is required. The nodes in the network not only acts as hosts but also as routers that discover and maintain routes to other nodes in the network. Quick and easy establishment of such networks make them feasible to be used in military, disaster area recovery and in other environments where no infrastructure exists or it has been destroyed. Since mobile nodes move in various directions causing existing links to break and the establishment of new routes, routing in such networks is a challenging task. The mobility (i.e. how nodes move) of mobile nodes plays a significant role on the performance of routing protocols. Routes between two communicating nodes may consist of multiple hops through other nodes in the network. Therefore, finding and maintaining routes in MANET is nontrivial. Several routing protocols have been developed for mobile ad hoc networks. Such protocols must deal with typical limitations of these networks which include low bandwidth, high power consumption, and high error rates. Ad hoc networks are characterized by multi-hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On- demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer models is used to study the interlayer interactions and their performance implications. We demonstrate that even though DSR and AODV share similar on-demand behavior, the differences in the protocol mechanisms can lead to significant performance differentials. In this paper we examine two on demand routing protocols AODV and DSR based on packet delivery ratio, normalized routing load, normalized MAC load, average end to end delay by varying the number of sources, speed and pause time.
