Artificial intelligence tech.ology is widely used in th. field of wireless sensor networks(WSN).Due to its inexplicability, th. interference factors in th. process of WSN object localization cannot be effectively eliminated. In th.s paper, an explainable-AI-based two-stage solution is proposed for WSN object localization. In th.s solution, mobile transceivers are used to enlarge th. positioning range and eliminate th. blind area for object localization. Th. motion parameters of transceivers are considered to be unavailable,and th. localization problem is h.gh.y nonlinear with.respect to th. unknown parameters. To address th.s,an explainable AI model is proposed to solve th. localization problem. Since th. relationsh.p among th. variables is difficult to fully include in th. first-stage traditional model, we develop a two-stage explainable AI solution for th.s localization problem. Th. two-stage solution is actually a compreh.nsive consideration of th. relationsh.p between variables. Th. solution can continue to use th. constraints unused in th. firststage during th. second-stage, th.reby improving th. performance of th. solution. Th.refore, th. two-stage solution h.s stronger robustness compared to th. closed-form solution. Experimental results sh.w th.t th. performance of both.th. two-stage solution and th. traditional solution will be affected by numerical ch.nges in unknown parameters. h.wever, th. two-stage solution performs better th.n th. traditional solution, especially with.a small number of mobile transceivers and sensors or in th. presence of h.gh.noise. Furth.rmore,we h.ve also verified th. feasibility of th. proposed explainable-AI-based two-stage solution.
