Tiny-sync: Tight time synchronization for wireless sensor networks

摘要: Time synchronization is a fundamental middleware service for any distributed system. Wireless sensor networks make extensive use of synchronized time in many contexts (e.g., data fusion, TDMA schedules, sleep periods, etc.). We propose method relevant wireless networks. The solution features minimal complexity network bandwidth, storage as well processing, and can achieve good accuracy. Especially networks, it also provides tight, deterministic bounds on offset clock drift. A synchronizing the entire presented. performance algorithm analyzed theoretically validated realistic testbed. results show that proposed outperforms existing algorithms terms precision resource requirements.
