Abstract: A routing-header-embedded low-cost time synchronization algorithm is proposed, which integrates the synchronization into the routing header of the message, and implements the synchronization by putting the precise time-stamp on routing message of both sides of transmitter and receiver. It also avoids the transmission of periodicity time synchronization message, and reduces the energy cost. Simulation experimental results show this algorithm is effective.

摘要： 提出一种嵌入路由报头的低功耗时间同步算法，该算法将时间同步集成到消息的路由报头中，通过在发送和接收端在路由消息上加盖精确的时间戳实现同步，从而消除了周期性时间同步消息的传输，减小了能量开销。仿真实验结果证明了该算法的有效性。
