Abstract
This paper presents a simple bias calibration method in wireless localization networks. Based on measured distances between a mobile sensor node and reference beacon sensor nodes fixed at known points, the proposed method estimates the bias error. To compute the bias error accurately, an optimization problem is formulated. Through numerous experiments, the performance of the proposed calibration algorithm is evaluated.
