摘要：
How to obtain accurate position of sensor node is still a challenging problem for wireless sensor networks (WSNs). This work concentrates on the problem of node localization with mobile anchor node, which is applied to broadcast beacon packets in the region of interest (ROI). Node localization scheme SAA-ERL (speed adaptive adjustment-energy ratio localization) for WSNs is realized in way of interactive communications. SAA scheme determines the suitable moving speed and direction for the mobile anchor node, while the ERL mechanism generates virtual hyper-spheres to help unknown nodes acquire their locations. Based on the quantitative analysis of the localizing performances, the guidelines for system parameters are obtained. Simulation results validate that when system parameters are jointly designed, SAA-ERL can be adapted to scenarios of diversified applications.
