Live multimedia streaming multicast in local area social networking environment of MANETs using SLIM+ Protocol

Evolution of multicast routing protocols for MANET are becoming the center of attraction for scholars of these days. This is due to varying applications areas, which in turn requires appropriate routing schemes for them. In the environment of mobile ad hoc networks, multicast communication efficiently saves the network resources. Adapting MANET as local area social networks allows new nodes to keep arriving and existing nodes departing the network as and when they like. Multicast routing protocols need to be readdressed to introduce the openness of the node set in such environments. The research paper focuses on evaluating the performance of routing scheme used by SLIM+ in multicast of live video or audio streaming to the freely interested devices or nodes, coming in the antenna rage. Performance metric used is Packet Delivery Ratio and End-to-End-Delay; by comparing it with its competitive and most commonly used tree based and mesh based multicast routing protocols. It then observed that SLIM+ remained successful in utmost delivery of data packets to the destinations thus took a little bit increased but insignificant time to advertise for live streaming. Whereas its counterpart MAODV failed in successful delivery of the data packets to the desired destinations and become free in less time. Whereas SLIM+ with its tree based structure competed with mesh based structured PUMA.
