Time Synchronization in WSNs with Noise: A Consensus Based Approach
This paper solves the problem of time synchronization in wireless sensor networks (WSNs) with noise. The consensus based approach is an improved average value based protocol. This algorithm, compared with the existing consensus-based synchronization approach, has the advantage of being totally distributed, asynchronous and robust to process and measurement noise. The main idea of this algorithm is to average the local information when a node has received all its neighbors information with taking noise into account to achieve a global synchronization. In particular, the simulation results can prove that all the nodes local information may converge to the average value or a bounded value range, which determines by the bound of noise.
