| Abstract: | An Ad hoc wireless mobile network is an infrastructureless mobile network that has no fixed routers. In typical Ad hoc network, multicast plays an important role. A critical challenge in the design of multicast in the Ad hoc network is the development of efficient routing protocols that can provide high-quality communication. On-demand multicast routing protocol(ODMRP) have better performance in Ad hoc. Based on ODMRP, a new Ad hoc multicast routing protocol IODMRP is proposed. This novel on-demand protocol enhances the routing algorism to make the route entries valid as long as possible and uses probing-based method to get the link state, which will make full use of the resource of Ad hoc network and improve the quality of communication. Simulation results show that IODMRP works efficiently. |
