摘　　要：针对无线传感器网络LEACH协议中簇首节点传输数据的冗余,使通信量过大,导致整个网络寿命短的问题,考虑到不同属性数据存在线性相关性,通过引入云理论和最小二乘的思想,提出了一种云加权—最小二乘(CW-LS)数据融合算法。仿真结果和分析表明:该算法能够消除冗余信息,使数据更加准确,减少了数据传输量,从而有效地延长了网络寿命。Aiming at problem of redundancy of data transmitted by cluster head nodes in LEACH protocol in wireless sensor networks（ WSNs）,which results in too much traffic and short entire network life,considering datas of different properties have linear correlation,by introducing the cloud theory and the idea of least squares,a kind of cloud weighted-least squares（ CW-LS）data fusion algorithm is put forward. Simulation results and analysis show that the algorithm can eliminate redundant information,which make the data more accurate,reduce amount of data transmission,and prolong network life effectively.
