Abstract
In this paper, we investigate the joint time synchronization and localization in wireless sensor networks. Specially, based on time-of-arrival (TOA), we consider a squared-range-based least squares formulation problem and propose a generalized trust region subproblem (GTRS) algorithm based joint time synchronization and localization, which can guarantee an optimal solution to the joint time synchronization and localization problem. Sufficient experiments results show that the estimation accuracy of the proposed algorithm outperforms the traditionalunconstraint linear least squares (ULLS) and nearly coincides with the Cramer-Rao lower bound (CRLB).
