Abstract :

Time synchronization is an important service in WSNs. existing time synchronization algorithms provide on average good synchronization between arbitrary nodes, however, as we show in this paper, close-by nodes in a network may be synchronized poorly. We propose the Distributed Time Synchronization Algorithm (DTSA) which is designed to provide accurately synchronized clocks between nearest-neighbours. DTSA works in a completely decentralized fashion: Every node periodically broadcasts its time information. Synchronization messages received from direct neighbours are used to calibrate the logical clock. The algorithm requires neither a tree topology nor a reference node, which makes it robust against link and node failures.
