Routing with AODV Protocol for Mobile ADHOC Network
M. Shyamala Devi, V. Rhymend Uthariaraj · 2011
One wireless network architecture that has received a lot of attention recently is the mobile ad hoc network (MANET).It is attractive because the network can be quickly deployed without the infrastructure of base stations. One main feature of MANET is that mobile hosts may communicate with each other through a sequence of wireless links (i.e., in a multihop manner). Mobile Ad hoc Networks are infrastructure less networks with dynamically changing topology. Several On- demand routing protocols have been proposed to facilitate the communication in these networks. Nodes of these networks function as routers, which discover and maintain routes to other nodes. The Ad hoc On-demand Distance Vector (AODV) is the widely used scalable protocol. But this shortest path algorithm prefers long hops, which results in routes with weak links. Hence route failure become frequent, even in case of less mobility, which degrades the network performance. In this paper we propose two modifications to the existing AODV. First to discover a reliable route (stable route), Next to minimize the delay in the re-route discovery. This reliable route discovery and seamless route maintenance mechanism will be implemented using GLOMOSIM (Global Mobile System Simulator) to obtain improvement in the network throughput.
