摘　　要：研究基于收包评价的无线传感器网络的部署,旨在用尽可能少的节点完成监测任务。提出了收包评价模型,用统计的方法研究无线传感器网络全网的数据收包情况,将收包视为正,丢包视为负,分析得出部署节点的具体数目,在满足部署需求或监测精度要求的前提下,使全网数据收包最大化。实验表明所提出的方法可以最大化网络的数据包接收。由于无线传感器网络中的丢包往往难以避免,收包评价适用于允许一定丢包率的实际部署,因而提出的方法具有广泛的现实意义,可以指导实际部署,以形成良好运行的无线传感器网络。This paper studied the deployment of wireless sensor network in order to find the minimum number of nodes to complete monitoring. This paper proposed the model of packet reception evaluation by using statistical method discuss the condition of packet reception of wireless sensor network. It treated packet reception as positive effect,treated packet loss as negative effect,and analysed the number of deployment sensor when satisfied the need of deployment or accuracy requirement of monitoring could maximize the packet reception. Packet reception evaluation is suitable for allowing packet loss reality deployment.Experiments show that the proposed method can maximum network packet reception. Because packet loss seems unavoidable in reality deployment,the method has extensive realistic significance. The method can guide reality deployment and forms well operational wireless sensor network.
