摘　　要：针对自组网的特点,提出一种单源互同步算法,使各节点动态地选择与本节点直接通信的节点中主时钟频率最大的节点作为帧同步的同步源,并向其锁钟,进而实现全网的帧同步与时钟同步。经测试验证,该算法在抗摧毁性能、同步收敛速度、时钟同步准确性和稳定性等方面具有较为突出的优势。According to the characteristic of Ad Hoc network, a single source synchronization algorithm is proposed. The algorithm can make the nodes choose the node with the fastest clock frequency as the source of frame synchronization, then lock clock to it, and realize frame synchronization and clock synchronization of the whole network. Experiments demonstrate that the algorithm has prominent advantage on survival capability, convergence speed, accuracy and stability of clock synchronization.

关 键 词：自组网 互同步 帧同步 时钟同步
