Transmission Range Effects of On-Demand Multicast Routing Protocol Multicast Communication for MANET

As laptop computers begin to dominate the marketplace, wireless adapters with varying bandwidth and range capabilities are being developed by hardware vendors. To provide multihop communication between these computers, ad hoc mobile networking is receiving increasing research interest. This paper deals with the analysis of the transmission range effects on On-Demand Multicast Routing Protocol (ODMRP) multicasting communication. Since ODMRP uses broadcast to transmit multicast data packets between nodes, the transmission range plays a key role in determining the performance of ODMRP. While increasing a node´s transmission range allows fewer hops between a source and destination and enhances overall network connectivity, it also increases the probability of collisions and reduces the effective bandwidth seen at individual nodes. Thereby this analysis study from the various graphs generated gives us a better clarity over the selections of the suitable network configuration.
