Abstract
The fault of Beacon nodes, as well as the interference in radio channel environment, will all affect the performance of localization. To eliminate these interference factors, a new distributed localization algorithm is proposed based on trust management. Firstly the algorithm splits WSN into several clusters with a certain cluster protocol, and then initiates the global trust rating (GTR) and local trust rating (LTR) of Beacon nodes. To get more precise location, it needs to localize frequently and update the GTR and LTR of beacon nodes. Theoretical analysis and simulation results show that the method can not only improve the precision of the positioning, but can also be used to examine abnormal beacon nodes and infer possible interference factors in wireless channel.
