Abstract: - Mobile Ad-hoc Network (MANET) is a self configuring network composed of mobile nodes without any fixed infrastructure. Group communications are important in Mobile Ad hoc Networks (MANET). Multicast is an efficient method for implementing group communications. But, it is big challenge to implement the well-organized and scalable multicast in MANET due to the difficulty in group membership scheme and multicast packet forwarding over a dynamic topology. EGMP uses a virtual-zone-based structure to implement scalable and efficient group membership scheme. A zone based bi-directional tree is constructed to achieve more efficient membership management and multicast delivery. The position information is used to guide the zone structure construction, multicast tree formation, and multicast packet forwarding, which efficiently reduce the overhead for route searching and tree structure maintenance. The main aim of this paper is to improve the performance of different multicasting approaching using Two-tier Overlay Multicast Architecture. Scalable overlay multicasting architecture approach to investigate the performance of Overlay multicast approach in Internet like environments based on realistic topologies. Overlay multicast architecture achieves close to optimal average resource utilization in such environments.
