Routing Protocol Based on Link Reliability for WSN

Abstract In this paper, defining link reliability strategy constructed by remain energy, and communication cost of nodes as topology weight to synthetically reflect the energy efficiency of dominator, an Energy-radio and communication cost route (ECCR) is proposed to solve the problem that the average energy consumption in cluster and minimum communication cost. We take node residual energy and distance between sink and node to compete cluster head, at the same time, in order to reduce the cluster head energy costs, link reliability and hop is used to establish topology. The experimental results show that the algorithm not only has the energy saved characters, but also ensures the reliability of topology links and extends the network life-cycle efficiently.
