摘　　要：研究无线传感器网络节点部署优化问题,传感器节点的部署在一定程度上决定了无线传感器网络的性能和使用寿命;针对随机部署的无线传感器节点,提出一种基于感知概率模型的节点部署方案;使用D-S证据理论通过计算对节点周围区域的综合感知概率,将虚拟力算法进行改造,使传感器节点向感知概率低的区域移动,实现对监测区域的最大覆盖;仿真结果表明,该部署算法实现节点合理分布,提高网络的覆盖率,减少节点的移动距离,达到延长网络使用寿命的目的。Wireless sensor network nodes deployment optimization problem is studied and sensor nodes deployment determines its capability and lifetime. This paper presents a nodes deployment scheme based on the perceived probability model aiming at the wireless sensor network nodes which are randomly deployed. The 13--S evidence theory is used to calculate the perceived probability in the area around the nodes and transform virtual force algorithm. This scheme moves the sensor nodes to the low perceived probability area and achieves the maximum coverage of the monitoring area. The simulation results show this deployment algorithm achieves the goal of the nodes reasonable dis-ribution with improving the network coverage and reducing the nodes movement distance and extends the lifetime.
