Abstract
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 cen-troid algorithm. The new algorithm mainly focuses on two aspects: On the one hand, the beacons during localiza-tion 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.关键词
