Abstract

Artificial intelligence technology is widely used in the field of wireless sensor networks(WSN).Due to its inexplicability,the interference factors in the process of WSN object localization cannot be ef-fectively eliminated.In this paper,an explainable-AI-based two-stage solution is proposed for WSN object localization.In this solution,mobile transceivers are used to enlarge the positioning range and eliminate the blind area for object localization.The motion parameters of transceivers are considered to be unavailable,and the localization problem is highly nonlinear with respect to the unknown parameters.To address this,an explainable AI model is proposed to solve the localization problem.Since the relationship among the variables is difficult to fully include in the first-stage traditional model,we develop a two-stage explainable AI solution for this localization problem.The two-stage solution is actually a comprehensive consideration of the relationship between variables.The solution can continue to use the constraints unused in the first-stage during the second-stage,thereby improving the performance of the solution.Therefore,the two-stage solution has stronger robustness compared to the closed-form solution.Experimental results show that the performance of both the two-stage solution and the traditional solution will be affected by numerical changes in unknown parameters.However,the two-stage solution performs better than the traditional solution,espe-cially with a small number of mobile transceivers and sensors or in the presence of high noise.Furthermore,we have also verified the feasibility of the proposed explainable-AI-based two-stage solution.
