The Mobile Ad hoc NETworks (MANETs) are self-organizing networks with dynamic topology. Flooding and Expanding Ring Search are two commonly used methods to search an interested node in Mobile Ad hoc Networks. Flooding is not suitable for large networks. In this paper, to take advantage of route discovery process based on conventional expanding ring search and to reduce broadcast overheads, we propose modified route discovery process for Improved Multicast Routing Protocol (IMRP). Because of reduction in broadcast overheads, protocol saves battery resources and promises better reliability and prolonged average lifetime for the network. The paper utilizes goodput, end-to-end delay, packet delivery fraction and residual energy under different scenarios that involve different parameters each time to examine and compare the behavior of IMRP with known Multicast Ad-hoc On-demand Distance Vector (MAODV) routing protocol. Our experimental results show that IMRP gives good results compared to MAODV.
