Localization Bias Reduction in Wireless Sensor Networks

Ji, Yiming; Yu, Changbin (Brad); Wei, Junming; Anderson, Brian

Description

In this paper, a novel bias-reduction method is proposed to analytically express and reduce the bias arising in sensor network localization problems, thereby improving the localization accuracy. The proposed bias-reduction method mixes Taylor series and a maximum-likelihood estimate and leads to an easily calculated analytical bias expression in terms of a known maximum-likelihood cost function. In contrast to existing contributions, this paper considers a sensor network as a whole when the...[Show more]
