针对无线分布式网络时钟同步中误差及信息的数目随层数增长过快的问题,提出基于管理和边界时钟广播的时钟同步算法(MBBS),详细介绍了MBBS的思想来源以及实现步骤.MBBS算法与PBS(pairwise broadcast synchronization)算法相比,虽然在每轮同步中增加一条同步信息,但是同步的从时钟数目增加了一层.实验结果表明,在多层网络拓扑下,MBBS减少了全局时钟同步所需的信息数目,提高了网络时钟同步的精度.
Aiming at the problem that the error and the number of information in wireless distributed network clock synchronization increase too fast with the number of layers, a clock synchronization algorithm (MBBS) based on management and boundary clock broadcasting is proposed, and the source of MBBS and its implementation steps are introduced in detail. Compared with the PBS (pairwise broadcast synchronization) algorithm, although one synchronization message is added in each round of synchronization, the number of synchronized slave clocks increases by one layer.The experimental results show that MBBS reduces the global clock synchronization under the multi-layer network topology The amount of information required increases the accuracy of network clock synchronization.
