Localization Accuracy Improved Methods for Range-Free Localization Schemes in Wireless Sensor Network

Abstract:

Location information is the most important for wireless sensor network (WSN). Due to the limitation of energy, cost and influence of environment, range-free localization schemes are more suitable for WSN despite of their low localization accuracy. Two methods, which are improved grids SCAN and multiple locating and averaging scheme, are presented to improve localization accuracy of range-free localization schemes and performed through performance evaluation based on ROCRSSI (Ring Overlapping based on Comparison of Received Signal Strength Indicator). By simulation it is concluded that ROCRSSI applying both methods can get better localization performances.
