摘　　要：无线多媒体传感器网络(Wireless Multimedia Senor Networks,WMSNs)的覆盖控制技术是传感器网络研究的关键问题,只有合理的部署传感器节点,才能达到对目标区域的全面监测。Voronoi图具有良好的区域划分性质,可以将监测区域划分成多个小的区域。所以,提出一种基于Voronoi算法的无线多媒体传感器网络的覆盖策略。通过Voronoi图形寻找新增传感器节点的坐标,计算出节点的质心点坐标,调整节点的方向。实现用比较少的节点,获得较高的覆盖率。Coverage technology of Wireless Multimedia Senor Networks（WMSNs） is the key problem of sensor net- work research. Only the rational deployment of sensor nodes can achieve full detection of the target areas. Voronoi diagram has good characteristics of regional division, and monitoring areas can be divided into some smaller areas. This paper presents a method based on Voronoi diagram coverage strategy in wireless multimedia sensor networks, the coordinates of the new nodes by Voronoi graph can be found. Then, the centroid coordinates of its node can be calculated and the direction of nodes can be adjusted, nodes as possible. and maximum coverage rate can be achieved by using a few
