An energy-efficient node selection scheme in wireless sensor networks

A cooperative node selection scheme based on credibility for the problem of cooperative node selection is proposed in wireless sensor networks. A credibility model is given considering the cluster head nodes of subjective reliability and obtained from other nodes impersonality and reliability, the model can provide accurate judgment for cluster head nodes. On this basis, a cooperative node selection scheme is proposed based on the credibility model considering the residual energy of nodes and the channel gain between nodes and data fusion center. Simulation results show that the proposed cooperative node selection scheme can balance the energy consumption of cluster nodes, and can reduce the total energy consumption.
