MANET is a set of mobile nodes connected by wireless link and are free to move dynamically and unpredictable in environment, but this dynamic nature of the network topology cause many challenges in MANET. Multicasting is an efficient way of providing necessary services for Ad hoc applications. Due to the dynamic nature of the network topology and restricted resources, finding and maintaining the routes for multicasting the data is still more challenging. Many Protocols have designed for multicasting in MANETs that On-Demand Multicast Routing Protocol is one of them. ODMRP is on-demand and mesh based protocol that uses forwarding group to establish a mesh for each multicasting group. In this paper, we discuss stable route selection in ODMRP for forwarding data. In basic ODMRP route selection function uses minimum delay. But in proposed approach we consider nodes energy in route selection from source to destination. For presenting PDR improvement in proposed approach, we discuss group size and mobility speed in control overhead and end to end delay. Result of simulation illustrate that our approach can improve stability of route due to energy consumption.
