A Simple Broadcast Synchronization in Low Energy-Consumption Distributed Systems

A synchronized network time is essential for many applications in low energy-consumption distributed systems such as data fusion and target tracking. This paper presents a simple broadcast synchronization method for low energy-consumption distributed systems. It´s based on sender-receiver scheme and uses only one time broadcast to synchronize all nodes in the distributed network. Also, this scheme uses a simple data processing method using deviation comparison to get the optimal parameters of skew and offset, which reduces the calculation complexity. Simulation results show that our method has greatly reduced energy consumption and obtained pretty good performance.
