Source Localization Using TDOA Measurements with Sensor Location Uncertainty
In this paper,the TDOA model for source localization in WSNs is considered.The total least-squares (TLS)algorithm is developed for location estimation of a stationary source with sensor location uncertainty.The uncertainty of the sensor location is formulated as a perturbation on the given sensor location.TLS is a least squares data modeling technique in which observational errors on both dependent and independent variables are taken into account.The sensitivity of the TLS solution is also analyzed. Simulation results show the good performance of the proposed algorithms.
