An entropy-based long-life multicast routing protocol in MAODV

A major aspect of mobile ad hoc network (MANET) is that the nodes move randomly, which requires the routing protocols in ad-hoc network to quickly respond to the network topology change in order to guarantee successful data packet delivery. MAODV (multicast ad hoc on-demand distance vector) routing protocol provides fast and efficient route establishment between mobile nodes that need to communicate with each other in MANET. MAODV has minimal control overhead and route acquisition latency. In addition to unicast routing, MAODV supports multicast and broadcast as well. In this paper, we present an entropy-based long-life multicast routing protocol in MAODV (EMAODV). The key idea of EMAODV algorithm is to construct the new metric-entropy and select the long-life multicast routing with the help of entropy metric to reduce the number of route reconstruction in MANET. The simulation results demonstrate that the proposed approach and parameters provide an accurate and efficient method of estimating and evaluating the route stability in dynamic mobile networks.
