A optimized distributed multicast routing protocol for wireless sensor network

Recent advance in Wireless Sensor Network (WSN) has led to totally different applications which attract a lot of attention. As addressed in [8], how to energy-efficient routing data packets to multi-sinks is a big challenge in WSN. While distributed multicasting technology is the most likely way to cope with this problem in nature due to the special characteristics of WSN. In this paper, we present a optimized distributed multicast routing protocol schema based on our former work DMRPS , termed oDMRPS, to dynamically build and maintain a multicast routing trees between sources and sinks. The primary simulation result shows that it performs much better than DMRPS, especially for numbers of grouped sinks with high density.
