网络化环境下多路径可能造成融合节点重复利用过去时刻的信息，导致过度数据融合和严重估计偏差，针对该问题，提出一种基于通信连接矩阵的传感器网络分布式信息融合算法，由每个时刻传感器网络的通信拓扑得到该时刻的连接矩阵，对连接矩阵进行计算可以找到并消除重复的先验信息，从而建立相应的分布式信息融合算法。仿真结果表明：该算法能够消除网络中重复信息对分布式信息融合性能造成的影响。

The multipath under network environment may cause the fusion node using the past information repeatedlywhich may lead to excessive data fusion and severe estimation bias.To solve the problema distributed information fusion algorithm based on communication connection matrix is presented.The connection matrix for a moment is obtained through the communication topology of the sensor network at that momentthe duplicate priori information is found and eliminated by calculating the connection matrix，and the corresponding distributed information fusion algorithm is established.The simulation results show that this algorithm can eliminate the influence of repeated information in the network to the fusion performance.
