Durable Distance Vector Multicasting Protocol for Mobile Ad Hoc Networks

In this paper, we propose a novel on-demand multicasting algorithm, "durable distance vector multicasting (DDVM)," for mobile ad hoc network (MANET). DDVM has a smaller routing-control overhead than link state routing (LSR) and provides a high delivery ratio for MANET with high mobility by adapting to dynamic topological changes. Furthermore, DDVM is energy-efficient in terms of "packet transmission efficiency." This is achieved by adding "combined path-durability" statistic into the routing-control information of distance vector routing (DVR). The routing-path duration statistic is computed in a fully distributed manner at each node in the network based on only local information from neighbour nodes. We show by simulation studies the effectiveness of DDVM compared with on-demand multicast routing protocol (ODMRP)
