A novel approach for indoor localisation is presented and it is composed of two mathematical models. One is a stochastic differential equation proposed to modify time of arrival of a mobile terminal (MT) to a base station (BS). Another is a multivariate optimisation model implemented to estimate the location of the MT by a random search algorithm. Through simulations using only the time of arrivals and measured coordinates of the BSs, the performance of the proposed scheme is evaluated by the measured coordinates of the 25 MTs. Simulation results demonstrate that the mean localisation error is only 0.5138 m and this method is very effective and applicable.
