  • An energy-efficient adaptive cooperative node selection scheme is proposed for energy-constrained wireless sensor networks. It determines the candidates of the Cooperative Node (CN) based on predetermined energy threshold, and then chooses the best node as the CN of Cluster Head Node (CHN) by considering the residual energy of the candidates as well as the channel state information. It can obtain the optimum energy threshold of different distances by minimizing the total energy consumption. Then the energy threshold is adaptively predetermined for minimizing the total energy consumption according to the distance between the CHN and the Data Fusion Center (DFC). The results of the theoretical analysis and simulation show that the proposed scheme can efficiently balance the transmission energy consumption and the circuit energy consumption so that it can efficiently reduce the total energy consumption, and can obtain the minimum of the total energy consumption.
