An Energy Efficient Routing Protocol Based on the Shortest Path in Mobile-Sink Wireless Sensor Networks

Abstract

Energy consumption phenomenon has always been noticed in sink-based wireless sensor networks. This paper explored an energy efficient routing protocol with a mobile sink based on the shortest path data transmission mode. According to the position of the sink node and the common nodes' ID in the network, we calculated the coordinate value of each node in the network. By comparing the coordinate values to choose the shortest path to forward the data. Simulation results show that this method can prolong the lifetime of the network and improve the energy utilization ratio of nodes.
