Abstract: A wireless sensor network(WSN) cooperative communication algorithm based on location(CCABL) is proposed,aiming at the problems of the energy efficiency and the selection of the cooperative communication nodes in the WSN.The CCABL selects the cooperative nodes and its member nodes according to the distance parameter,introducing the ideas of the data fusion and clustering.By fussing its members' data,the cooperative node participates in cooperative communication by the F/R(forward/reverse) cooperation.Theoretical analysis and NS2 simulation results show that compared with the data fusion algorithm and the LEACH clustering algorithm,the CCABL can not only improve the energy efficiency highly,but also balance the node's energy consumption and prolong the network lifetime.Meanwhile the CCABL is easy to be realized and has lower control load.
