Abstract—Recently, group communications over Mobile Ad hoc Networks (MANETs) have received considerable attention. Group communication needs support of multicast routing protocols for simultaneous delivery information of group of receivers. Thus, designing effective and efficient multicast routing protocol is necessary to support this kind of applications. Several efforts have been adopted to improve multicast routing. However, most of them did not consider the scalability issue. In this paper, we propose a novel Scalable Geographic Multicast Routing Protocol (SGMRP) to improve the scalability of multicast routing with reduced overhead. SGMRP uses virtual clustering strategy to implement scalable routing and efficient group management. This scheme based on partitioning the network into sectorial zones. The proposed solution performs efficient packet forwarding with reduced communication overhead. This scheme reduces the number of participating nodes and eliminates the duplicate packets. Compared with on Demand Multicast Routing Protocol (ODMRP) and Efficient Geographic Multicast Protocol (EGMP), simulation results show that SGMRP delivers more packets with significantly reduced overhead regardless of the network size, mobility speed and number of multicast members.
