摘　　要：针对节点高密度随机抛撒的传感器网络,提出了一种基于数据融合的部署策略,采用D-S融合感知模型,将高密度随机部署问题转化为一定覆盖质量下的三角部署问题,将初始随机抛撒的传感器节点划分为三角网格,网格内部区域采用证据理论(D-S理论)进行数据融合,将数据融合的范围控制在部署网格内,减少协作能耗。仿真结果表明,算法能有效提高检测的可靠性,覆盖冗余度较小,能耗均衡,延长了网络的寿命。To the high-density,random deployed sensor network,a deployment strategy based on data fusion is proposed,in which D-S fusion perceptual model is used,and the high-density random deployment algorithm is transformed into a triangle deployment issue under certain quality of coverage.All the original sensor nodes are divided into triangular grids,the scope of data fusion is controlled within the deployment of grid by D-S theory for reducing cooperation energy.The simulation results show that the algorithm can effectively improve the detection reliability with a small redundancy,average energy consumption,and extended life of network.
