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.
