摘 要: 针对随机部署的有向传感器节点,建立基于有向传感器节点的感知概率模型.采用分布式算法,通过节点间的联合感知概率移动有向传感器节点,提高待监测区域内目标点被感知到的概率.本文提出可移动的节点部署算法,该算法使用较少的节点实现对目标区域的合理覆盖,并提高总体覆盖效果.仿真结果表明,该算法有效地减少了有向传感器节点的使用,同时保证了较好的覆盖效果. According to the random deployment of directed sensor nodes,the directed sensor nodes based on the perception probability model is established. The distributed algorithm according to perception probability of nodes moves the sensor nodes and improves the perception probability of targets in monitoring area. The mobile nodes deployment algorithm using fewer nodes to achieve reasonable coverage of the target area and improving the effect of the overall coverage is designed. The simulation results show that this algorithm can effectively reduce the use of sensor nodes,while ensuring a better coverage effect.
