Abstract: In wireless sensor networks,using energy harvesting technology can theoretically extend infinitely the life of the nodes.Based on this technology,this paper presented a new opportunistic routing algorithm called energy potential opportunistic routing (EPOR) algorithm.First,the algorithm uses expected transmission count between the transmission node and the destination node to measure the distance between them.Then,the sum of the residual energy and the harvested energy of the node is used to express the energy potential of the node.Finally,the expected transmission count and the potential energy of the node are used to determine the back off time of the node.The node which has the shortest back off time is the transmission node.Theoretical analysis and simulation results show that this algorithm can not only prolong the life of the network,but also significantly improve the energy balance of the nodes in the network.
