无线传感器网络中TPSN时钟同步算法的研究和改进

In this paper, basic concepts of wireless sensor network time synchronization are introduced and TPSN(Timing-sync Protocol For Sensor Network) is focused to described. For TPSN unreliable, synchronization overhead and other issues, one improved time synchronization algorithm based on TPSN is given out in this paper. Compared with traditional TPSN mechanism, simulation shows that new algorithm can predict the synchronization error, reduce the synchronization overhead and improve synchronization reliability.
