SODMRP: Stable On-Demand Multicast Routing Protocol

A mobile ad hoc network (MANET) is a dynamically reconfigurable wireless network that does not have a fixed infrastructure.The grouporiented services are one of the important application classes that are adopted by mobile ad hoc networks (MANETs). To support such services, multicast routing is used. But, stable multicast routing is difficult in MANETs due to limited resources and mobility of nodes. This paper proposes an energy-aware approach to develop a stable multicast routing protocol. By offering some modifications over ODMRP protocol, we involve nodes’ energy information in the proposed protocol, to increase routes stability. Simulation results show that the proposed protocol improves route stability and hence leads to more packet delivery rate (PDR), more throughput and longer route life time, in compare with ODMRP.
