In this paper1, we propose a simple method to introduce a-priori information in position estimation for mobile ad hoc and sensor networks, in order to improve the estimation accuracy. The a-priori information is derived from the movement of the mobile node with respect to the position of fixed anchor nodes, and it is exploited to perform Bayesian estimation procedure. Numerical simulation results corroborate the effectiveness of the proposed technique, which outperforms the maximum likelihood one.
