摘　　要：针对无线传感器网络能量有效性和协同通信节点选取问题,提出基于位置的无线传感器网络协同通信算法(CCABL).该算法通过距离参数选取协同节点及其成员节点,并引入数据融合和分簇思想.协同节点融合成员节点数据,采用F/R(forward/reverse)协同通信传输数据.理论分析和NS2仿真验证表明,与数据融合算法和LEACH分簇算法相比,CCABL算法不仅有效地提高了能量有效性,而且节点能量消耗更加均衡,网络生存期长,同时算法实现简单,控制开销低.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.
