Abstract: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.
