基于矩阵的无线传感器网络数据融合方案

摘要

Data fusion is an important means to reduce energy consumption of wireless sensor networks( WSNs), and in order to save energy of WSNs nodes,a layer-cluster data fusion scheme based on matrix theory is proposed. Residual energy and relative density of nodes are considered in election of cluster head,besides,datas collected by cluster member nodes are fused by using matrix operations respectively. At last,this new scheme is compared with traditional LEACH protocol,and experimental results show that compared with traditional LEACH protocol,the proposed scheme can effectively reduce data redundancy and amount of data transmission,save energy consumption of nodes and thereby extend lifetime of network.%数据融合是降低无线传感器网络（ WSNs）能耗的重要手段，为了有效地节省WSNs节点的能量，提出一种基于矩阵的层簇式数据融合方案。在簇头选举时，考虑节点的剩余能量和相对密度，并利用矩阵运算对簇内成员节点采集的数据进行数据融合处理。最后将所提方案与传统的LEACH协议进行仿真比较，实验结果表明：相比于传统的LEACH协议，所提方案可以有效降低数据冗余，减少数据传输量，节约节点能耗，进而延长网络生存期。
