Network data fusion and cluster are effective technologies to reduce energy consumption of Wireless Sensor Netw ork( WSN),how ever,clustering produces extra delays in the process of data aggregation,and the problem can be solved by the modified netw ork structure. A Delay-aw are Netw ork Structure for WSNs w ith Data Fusion( DANSDF) is proposed. The proposed structure organizes sensor nodes into clusters of different sizes,each cluster can communicate w ith the fusion center in an interleaved manner. Simulation results show that compared w ith Low Energy Adaptive Clustering Hierarchy( LEACH),Delay-aw are Data Collection Netw ork Structure( DADCNS) the tw o netw ork structures,DANSDF can reduce the delay in the process of data fusion,and can keep a low energy consumption.
