Abstract
Wireless sensor network technology for mine personnel and vehicles is an important technology for accurate positioning means of mine work safety,but because of the space of underground roadway semi-closed char-acteristics and wireless signal transmission in the tunnel multipath fading, the traditional planar and three-dimensional localization algorithm cannot be fully applicable to the underground tunnel for mobile node localization. To solve this problem, an improved weighted centroid localization algorithm is proposed based on RSSI. The algorithm is based on node coverage model tunnel on the tunnel, fully considered with node heterogeneity and mobility,imported heterogeneous node communication radius’ influence for the assignment of weights,and adjusted weights. Simulation results show that the algorithm has higher location accuracy comparing with ordinary weighted centroid and more suitable for underground tunnel,highway and rail tunnels.关键词
