摘要
为满足矿井安全监测需要,本文针对井下类拱形巷道环境提出了一种改进的三维DV-Hop算法和加权质心混合算法。该算法主要从两个方面改进,信标节点使用五个通信半径广播自身位置信息,使得信标节点与其邻居节点间的跳数可以为小数;引入权值因子,计算未知节点坐标。
In order to meet the requirement of safety monitoring of the underground tunnel, in view of the arch tunnel, this paper puts forward an improved mixed localization algorithm of DV-Hop algorithm and weighted centroid algorithm. The new algorithm mainly focuses on two aspects： On the one hand, the beacons during localization use quintuple communication radius to make sure that the hops between beacons and their neighbor nodes can be decimal. On the other hand, a weighting factor is introduced to calculate the coordinates of unknown nodes. The simulation results shown that the improved algorithm has obviously better locating performance.
