| 摘 要： | 在无线传感网络(WSN)中,节点的定位是一个非常之关键的问题,而DV-Hop算法是节点定位诸多算法中最主要的一个算法,但它计算未知节点到锚节点的距离时存在些许问题,所以提出了一个新的计算节点间距离的方法,考虑到在未知节点到锚节点路径上三个连续的节点所形成的角度的影响,使得距离的计算更精确.通过仿真可以得知这个改进算法能有效地提高未知节点定位的覆盖率和精度.

| Abstract: | The node positioning is a very pivotal problem in the wireless sensor network, and the DV-Hop algorithm the most important algorithm in the node positioning. There is some error when calculate the distance between unknown node and anchor node, so the essay proposed a improve algorithm. The algorithm involved the effect of the angle formed by three consecutive nodes in the path of unknown nodes to anchor nodes. We can know that the improved algorithm can increase coverage rate and location precision effectively from simulation. |
