A Consensus-Based Distributed Clock Synchronization For Wireless Sensor Network

With the increasing demand and the consensus algorithm widely used for clock synchronization in wireless sensor network, we propose a consensus-based distributed clock synchronization protocol (CDCS). The protocol based on the random broadcast scheme has advantage of being asynchronous, robust to node failure or appearance and totally distributed. We consider a network represented by a directed graph, which is simplified according to rules of the protocol, and simulations are presented to evaluate different synchronization schemes, where the proposed protocol shows promising performance.
