A Mobile Anchor Assisted Localization Mechanism for Wireless Sensor Networks

Point-based approach is a well-known localization approach in Wireless Sensor Networks (WSNs). However, by applying the point-based approach, the communication disk (communication range) of each sensor has to be passed through by the mobile anchor twice at least. To address this problem, this paper presents a Rapid Localization (RL) scheme which aims at reducing the time duration required for each node to determine its location. Experimental results show that the proposed RL scheme has better performance than existing localization scheme in terms of the average location error, time required of localization, and energy conservation.
