Abstract:- Group communications is the most common requirement in today’s advanced wireless mobile communications. Several mobile applications in MANETs (Mobile Ad hoc Networks) involve group communications among zones and as well as nodes. The most compromising technique for achieving group communications is multicasting and because of advanced developments in technologies multicasting becomes as one of the most important networking service. However implementing a robust and efficient multicasting is a very challenging task because of multicasting of packet forwarding and efficient group management. Therefore in this paper we propose a systematic novel method known as EGMP (Efficient Geographic Multicast Protocol). To implement scalable and efficient group membership scheme a virtual a virtual-zone-based structure is used. In EGMP, to achieve most efficient group management a zone based bi directional tree is implemented. Here the position information of each individual node is used to construct the zone, multicast tree construction, and multicast packet forwarding, which greatly decreases the overhead for route searching and tree structure maintenance. An efficient distributed algorithm is used in efficient EGMP to support dynamic changes to the multicast group during the construction of tree and effectively allows overlapping join/leave operations. Finally, the simulation results demonstrates that EGMP has excellent packet delivery ratio, low control overhead and multicast group joining delay under all test scenarios, and EGMP is scalable for both group size and network size.
