Claim:
1. A method for facilitating timing synchronization in a network, comprising, at a network node: updating a local timing value of the network node iteratively based on synchronization signals from neighboring network nodes to obtain synchronization with respective remote timing values of the neighboring network nodes; determining that the local timing value is in a stable state, wherein it is determined that the local timing value is in the stable state when a difference between two most recent deltas is smaller than a predetermined threshold, and wherein each of the two most recent deltas is defined as a difference between two consecutive local timing values of the network node; calculating a bias due to propagation delays of the synchronization signals based on a plurality of local timing values from the local timing values obtained in a plurality of iterations of said updating; and correcting the local timing value based on the bias.
