摘要 提出了一种改进的时间同步算法IRBS(improved references broadcast synchronization),它是在RBS算法的基础上,根据接收节点的时间值,估算出实际时间值,并利用估计时间来实现时间的同步。仿真结果表明,IRBS算法能够缩小时间误差,有效提高时间同步的精度。 IRBS algorithm was proposed on RBS. According to receiver node time, IRBS estimate its real time. During its calculation of two nodes'time difference, it realizea time synchronization by the estimating time. Simulation result shows IRBS algorithm can reduce time error and improve time synchronization precision.
