Cross Layer based AODV (CLAODV) Routing for MANET

Abstract

Communication with mobility has become essential as nowadays everyone wants to get connected anytime with outside world. Further places with no network infrastructure Mobile Adhoc Networks, called MANETs can play a vital role. A MANET is a network form by a collection of wireless nodes capable of exchanging information without having a fixed network infra- structure. MANET has many applications in scenario such as in disaster man- agreement, battle field where exchange of information has to be done by mobile units without relying on any fixed network infrastructure. With the rapid growth of wireless technology, MANET themselves has become an independent wide area of research. However, this paper mainly focuses on issue of routing as routing protocol plays a vital role in performance of MANET. This paper uses AODV protocol as routing protocol for its study as AODV is widely used as routing protocol for MANET. ADOV uses flooding of Route Request packet in search of path and we know that flooding of packets degrades the performance of the network due to high congestion. Therefore, this paper mainly extends the working mechanism of AODV by implementing a Cross Layer approach term as CLAODV to reduce the flooding of Route Request. This enhancement is done in order to get better Quality of Services (QoS) in terms Throughput and Average Delay. The performance of the Extended AODV protocol is evaluated through NS2simulation.
