Abstract

Measurement error is known to degrade remarkably the target localization accuracy. Cooperative localization using time difference of arrival (TDOA) measurements is a major research subject for positioning applications which is concerned by this paper to reduce the loss in localization accuracy owing to measurement error. In this paper we investigate neighborhood collaboration based cooperative localization algorithm with significantly lower computational complexity of all targets in wireless sensor network. We evidently demonstrate the superior trade-off between estimation performance and computational complexity of the proposed algorithm. The proposed iterative algorithm results incorrectly converged and the converged solution would approximately be the optimum solution when the measurement errors are sufficiently small. Simulations are used to confirm and support the theoretical development.
