Time Synchronization For Wireless Sensor Networks Based On Local Level Structure
Shi Weiren, Yang Zhang, Pengcheng Deng · 2006
Time synchronization is a critical piece of infrastructure for wireless sensor networks. The existing time synchronization protocols such as GPS and NTP require powerful hardware to support aren't fit to sensor network. This paper analyzes the characteristic of sensor network, propose a time synchronization algorithm based on local level structure. Experiment shows that this method is feasible and can be used to wireless sensor networks.
