Abstract The ability to automatically locate sensor nodes is essential in many Wireless Sensor Network WSN applications. To reduce the number of beacons, many mobile-assisted approaches have been proposed. Current mobile-assisted approaches for localization require special hardware or belong to centralized localization algorithms involving some deterministic approaches due to the fact that they explicitly consider the impreciseness of location estimates. In this paper, we first propose a range-free, distributed and probabilistic Mobile Beacon-assisted Localization MBL approach for static WSNs. Then, we propose another approach based on MBL, called Adapting MBL A-MBL, to increase the efficiency and accuracy of MBL by adapting the size of sample sets and the parameter of the dynamic model during the estimation process. Evaluation results show that the accuracy of MBL and A-MBL outperform both Mobile and Static sensor network Localization MSL and Arrival and Departure Overlap ADO when both of them use only a single mobile beacon for localization in static WSNs.
