Abstract. In this paper, we focus on maximizing network lifetime of Multi-Sink Wireless Sensor Networks without compromising on reliability requirements. We propose Multi-Sink Multi-Path (MSMP) protocol which achieves the desired reliability by selecting the sink nodes based on their Total Reaching Probabilities (TRPs) and using multiple paths for forwarding to each selected sink. MSMP maximizes the network lifetime by reducing the load on the one hop neighbors of the source node. In addition, MSMP shuffles among all the ...
