Mobile Anchor Route Scheduling with an Iterative Sensor Positioning Algorithm in Wireless Sensor Networks

Locating deployed sensor nodes in wireless networks is a crucial issue for general environmental monitoring applications. Most current positioning technologies use stationary anchors to compute the positions of nodes. However, placing static area not trivial job, especially hazardous environments. Applying mobile anchor good solution. This paper proposes an iterative (ISP) algorithm that uses neighboring-positioned assist locating unknown In addition, route scheduling method, named MARS, also proposed shorten traveling distance anchor. MARS projection mechanism and ISP reduce distance. Simulation results indicate can by about 21–49% compared with SCAN method. unfavorable scenario mechanism, still provides 34% less than The anchor, when applying able locate all only 45% 70% required one using method favorable algorithm, while reducing 15% 21% algorithm. non-ideal signal scenario, size 53% 74% Triangulation
