Combination Synchronization Protocol with Center Nodes in Device-to-Device Communication System
Jiangsheng Fan, Yafeng Wang, Youxiong Lu · 2016
In this paper, we propose a hybrid synchronous algorithm based on the combination of distributed and centralized algorithm.First of all, we put forward the concept of local cluster and generalized local cluster.The cluster is a collection of synchronous UE meeting certain conditions and has a center UE.Through this mechanism, we can finish many synchronous parts in advance what we call pre-synchronization which can reduce system latency.When we need system synchronization, we will use the flooding time synchronous protocol.The algorithm has low latency as well as high accuracy and good robustness.
