Qualified Stateless Multicast Routing Protocol for Enhancing the Network Lifetime in MANET

Multicast routing is more effective than unicast routing as it transmits a single copy of message to all its group members within single transmission. Multicast routing protocols require the individual nodes to maintain the state information, as they typically rely on the creation of multicast tree or mesh. Maintaining this state information creates a large amount of communication, processing, memory overhead and complexity in finding the geographic location of the neighbor nodes. Since every node in manet has to perform the function of the router, some nodes may die early due to the lack of energy leading to the disconnection of the network. Thus we have developed a Qualified Stateless Multicast Routing Protocol (QSMRP) that simply uses the addresses of the multicast group members stored in the packet header that enable the receivers to select the best path for packet transmission and also enhances the lifetime of the network by finding the routing solutions that minimizes the energy of the nodes in the network.
