摘要：Recent work shows sink mobility can improve the energy efficiency in wireless sensor networks. However, the mobile sink often leads to increasing the energy consumption and routing protocol variation, so support mobile sinks, energy efficient routing protocol is essential. In this light, the Minimum energy consumption relay node is proposed, which plays a import role to broadcasting the estimated sink's location information to the nodes which take data packets to establish the efficient routing. Meanwhile the periodic broadcast scheme to provide the sink's location information is broadcast to entire network in order to increase the data packet delivery ratio. The simulation and experiments show that the proposed routing algorithm reduces the energy consumption of the network node, and at the same time keep the network higher data rate.
