Abstract
Time synchronization is a critical piece of infrastructure for any distributed system. Distributed, wireless sensor networks make extensive use of synchronized time, but often have unique requirements in the scope, lifetime, and precision of the synchronization achieved, as well as the time and energy required to achieve it. Existing time synchronization methods need to be extended to meet these new needs. We outline the synchronization requirements of future sensor networks and present an implementation of our own lowpower synchronization scheme, post-facto synchronization. We also describe an experiment that characterizes its performance for creating short-lived and localized but highprecision synchronization using very little energy. 1.
