Range-Based Clock Synchronization Protocol for Wireless Sensor Networks

Zhetao Li, Renfa Li and Liangjiao Liu

Abstract:
This study presents a novel range-based clock synchronization protocol by exploiting non-synchronized TDOA. It combines the method of Network Time Protocol (NTP) with round-trip TDOA. By applying round-trip TDOA repeatedly, all nodes in network efficiently synchronize to each other. Furthermore, clock synchronization and ranging can be performed simultaneously. Simulation results show it outperforms Timing-sync Protocol for Sensor Networks (TPSN) and Reference Broadcast Synchronization (RBS) in terms of the number of message exchanges and synchronization error.
