Time synchronization of wireless sensor networks under random environment

This technical note addresses the distributed time synchronization problem for wireless sensor network (WSN) and personal area network (PAN) under randomly switching topologies, respectively. The coordination goal here is to make the clock speed of each sensor asymptotically converges to a same value and the clock offset of each sensor vanishes asymptotically. To achieve this goal, several distributed algorithms based on some updating laws are proposed, while we do not focus on the convergence analysis. Finally, some simulation examples are given to show the effectiveness of the proposed algorithms.
