Implementation of Selective Forwarding Technique on AODV Protocol in MANET

A mobile ad hoc network (MANET) is a collection of wireless mobile nodes. MANET nodes without the need for any centralized control function are able to create a cooperative network among them. The change in topology in MANET makes routing as a crucial issue in the design of the MANET. Because of the decentralized infrastructure, MANET has to rely on flooding based route discovery/maintenance mechanisms, which generates control overhead. In this paper, we have studied the routing overhead and proposed a routing protocol in which each node exchange “Hello message” with its immediate neighbor. Hello message contains list of one hope neighbor of sender node. On the basis of this information Multi point Relay (MPR) point will be decided for that node. MPR points of a node are the minimal set of one hop node through which all two hops can be covered. Thus we can limit the routing overhead due to flooding of message.
