摘要
为了改善DV—Hop算法对节点的定位精度和提高覆盖率，对DV—Hop定位算法中未知节点到锚节点间距离计算方法进行了改进，提出了一种新的距离计算方法，并对改进算法和原算法进行了对比仿真。仿真结果表明了改进算法的有效性。
In order to improve the accuracy of node localization and coverage fraction of DV-Hop algorithm,this article has presented a new calculation method of the distance from unknown node to the anchor node in the original algorithm. Simulation contrast is made between the improved algorithm and the original algorithm. The simulation result has proved this algorithm＇s validity.
