A Novel Time Synchronization Algorithm Based On Synchronizer Of Clustering Architecture

Most of time synchronization algorithms were based on hierarchical structure, and trade using packet exchanging or complex calculating for promoting precision, so when the density of nodes becomes larger, there are much packets switching and power consumption. At the same time, channel collision will be much worse and convergence time is slow for all nodes of time synchronization. This paper presents a novel time synchronization algorithm based on synchronizer of clustering architecture. We adopt improved RBS approach based on the synchronizer, which reduce messages overhead efficiently. Meanwhile, when the nodes density is increasing and all nodes synchronize, channel's utilization is more efficient than hierarchical method. Finally, performance of this algorithm is illustrated by simulative experiment.
