Fully distributed clock synchronization in wide-range TDMA Ad-Hoc networks

In this paper, a fully distributed synchronization scheme for wide-range TDMA Ad-Hoc networks is described. This synchronization scheme provides a simple algorithm with low overhead requirements to achieve high clock synchronization accuracy in a fully distributed approach. Our work is based on the clock sampling mutual network synchronization (CS-MNS) algorithm. It extends it by including the propagation delay between nodes in the problem formulation and by providing a detailed signaling framework to carry out synchronization information. The study based on OPNET simulations finds that 1us clock synchronization accuracy can be achieved in long range TDMA MANETs.
