| 摘 要： | 针对DV-Hop定位算法以平均跳段距离代替实际直线距离而导致定位误差较大这一问题,提出了一种改进的DV-Hop定位算法.在改进算法中,锚节点通过实际距离和估计距离的误差来修正每跳平均距离.改进DV-Hop节点坐标计算方法,摒弃传统的三边定位算法而采用新的二维双曲线定位算法计算节点坐标.最后求得包含误差修正值的最终节点坐...

| Abstract: | Conventional DV-Hop localization algorithm considers the average hop distance as the expected distance,so it will lead to larger error in position.In response to this problem,an improved DV-Hop localization algorithm is proposed.In the improved algorithm,anchor nodes correct the average hop distance by the total error between calculated distances and estimated distances.Improving the method of nodes coordinates computing,we will not adopt traditional Triangulation algorithm but use 2-D Hyperbolic location a... |
