Mobile Ad-hoc Network (MANET) is a group of wireless nodes that are distributed without relying on any standing network infrastructure. Group communication plays an important role in MANETs. To implement this group communication, we propose an Efficient Geographic Multicast Routing protocol (EGMP) with the help of virtual zone based structure. This EGMP protocol deals with the position information which is used to construct zone structure, multicast tree and multicast packet forwarding. The performance metrics such as Packet Delivery Ratio (PDR), End to End delay and Control Overhead of EGMP are also evaluated through simulations and quantitative analysis by varying number of nodes, zone size and group size. Our simulation result shows that EGMP has high packet delivery ratio, low control overhead and multicast group joining delay under all test scenarios when compared with On-Demand Multicast Routing Protocol (ODMRP) and Scalable Position Based Multicast Routing Protocol (SPBM), and is scalable to group size.
