| 摘 要： | 针对DV-Hop算法在网络拓扑结构不规则的环境中存在较大误差的问题,提出改进的DV-Hop算法,该算法通过引入全网平均每跳误差修正值获得未知节点到锚节点的有效距离,可避免后续计算过程中误差的累积。利用MATLAB7.5.0仿真平台对DV-Hop算法和改进算法进行仿真分析的结果表明,在没有增加通信开销的基础上,随着锚节点所占比例的增加,改进后的DV-Hop算法比原DV-Hop算法在定位精度、覆盖率及稳定性上都得到了大大提高。

| Abstract: | Aiming at errors of DVHop algorithm in anomalistic topological structure of networks, the improved DVHop al gorithm is expounded. By introduction of error correction value of average hop distance of the network, the operating dis tance between unknown node and anchor node is obtained, which helps to avoid error accumulation in the process of calcula tion. The simulation experiment shows that on the basis of not increasing the communication cost, improved DVHop algo rithm is superior to DVHop algorithm in localization accuracy, percentage of coverage and stability with the increased per centage of anchor node. |
