Abstract
An improved method about range-based time synchronization (RTS) was proposed in this paper. By exploiting the synchronization redundancy between nodes, we proposed head-end modification and end-end modification to enhance time synchronization precision. Simulation results show improved RTS outperforms in terms of accuracy than RTS.
