| 摘 要： | 针对无线传感器网络中DV-Hop定位算法在未知节点到锚节点距离计算中的不足,提出了一种新的距离计算方法。该算法考虑了未知节点到锚节点路径中相邻三个节点组成的夹角对距离的影响,从而更精确计算出距离,并对改进算法和原算法进行了对比仿真。仿真结果表明,改进算法有效地提高了节点的定位精度和覆盖率.

| Abstract: | The essay proposed a new calculating method of distance to solve some problems of DV-Hop algorithm when used to compute the distance of unknown nodes to anchor nodes in the wireless sensor network.The algorithm involved the effect of the angle formed by three consecutive nodes in the path of unknown nodes to anchor nodes,on distance.So the distance can be calculated more accurately,and simulation contrast between the improved algorithm and the original one can be made.The simulation result proved that the i... |
