Concert of Broadcasting Techniques in MANET

Broadcasting is the process in which a source node sends a message to all other nodes in MANET. Network wide broadcasting in Mobile Ad Hoc Networks provides important control and route establishment functionality for a number of unicast and multicast protocols. This paper presents an overview of Flooding; Probability based broadcast forwarding, Location based and Neighbor Knowledge method broadcasting techniques in mobile ad hoc networks. The simulations are designed to pinpoint, in each category, specific failures to network conditions that are relevant to MANETs. For instance, protocols such as dynamic source routing (DSR), ad hoc on demand distance vector (AODV), use broadcasting to establish routes. Broadcasting MANET poses more challenges than in wired networks due to node mobility and scarce system resources. Because of the mobility there is no single optimal scheme for all scenarios.
