ABSTRACT
Group communications are important in Mobile ad hoc Networks (MANET).A mobile ad hoc network (MANET), is a dynamic self-configurable wireless network, which has no fixed infrastructure or central administration. Multicast is an efficient method for implementing group communications. By the development of new network technologies, multicasting has become one of the important networking services. Designing multicast routing protocol is a big challenge due to difficulty in achieving group membership management, packet forwarding and maintenance of multicast structure over the dynamic network topology. In order to implement group communication, Efficient Geographic Multicasting Protocol (EGMP) came into existence. EGMP uses a hierarchical structure to implement scalable and efficient group membership management. And a network-range zone-based bi-directional tree is constructed to achieve a more efficient multicast delivery. The position information is used to guide the hierarchical structure building, multicast tree construction and multicast packet forwarding, which efficiently reduces the overhead for route searching and tree structure maintenance. EGMP has high packet delivery ratio, low control overhead and multicast group joining delay under all test scenarios, and is scalable to both group size and network size
