| 摘 要： | 在TDMA体制下的移动网状自组织网络中,为了解决网络时隙同步问题,提出了一种不依赖GPS授时的网络时隙互同步算法。各节点通过计算相邻节点的时隙偏差,通过加权计算并调整本节点的时隙位置,使网内各节点的时隙起始都调整到同一位置上,达到时隙的互同步。通过仿真和实验,分析并验证了移动自组织网络时隙互同步的收敛性能和抗干扰性能。

| Abstract: | In order to resolve the problems of slot synchronization in TDMA mobile ad hoc networks,a method of slot co-synchronization is proposed for mobile ad hoc networks without GPS.The realization of algorithm is presented.Each node measures the offsets of slot starting time with respect to other nodes,calculates the weighted average value and adjusts its own slot starting time.Finally every node has the same slot starting time and the slot synchronization of ad hoc networks is achieved.Simulation and experiment results show the convergence and robustness of the proposed algorithm. |
