Multicasting Hierarchical Routing Protocol of Mobile Ad Hoc Networks

? A Mobile adhoc network (MANETs) is a collection of wireless mobile nodes dynamically forming a network without using any centralized access point, infrastructure or centralized administration multicasting is an useful operation that facilitates group communication efficient and scalable .Multicast routing in MANETs is a difficult issue. In addition to the conventional multicast routing algorithms, recent protocols have adopted are overlays, backbone-based, and stateless.To enhance performance and enable scalability, we have proposed a framework for hierarchical multicasting in MANETs environment. Two classes of hierarchical multicasting approaches termed as domain based and overlay-based are proposed. We have considered a verity of approaches that are suitable for different mobility patterns and multicast group size.
