MR. BIN: Multicast Routing with Branch Information Nodes for wireless sensor networks

We propose a novel multicast protocol, named Multicast Routing with Branch Information Nodes (MR. BIN) for wireless sensor networks (WSNs). Addressing the various overhead issues of existing WSN multicast protocols, MR. BIN uses a hybrid approach of geographic unicast routing and state-based multicast routing. It achieves an optimal tradeoff among the overhead of the intermediate nodes' states, packet header size, computation time, and energy consumption and balance. Through both analysis and extensive simulations, we validate that MR. BIN outperforms existing multicast WSN protocols in the aforementioned aspects.
