提出了一种动态分簇时间同步算法(DCTS),首先针对无线测距网络的特点,传输数据量较少,簇首节点无需进行大量数据融合情况下,对LEACH分簇路由算法进行改进,提出了GLEACH分簇路由算法,并使用GLEACH分簇路由算法将整个网络分成不同的簇,以基站与簇首节点为参考节点,采用类似于TPSN双向同步机制,逐级同步,实现全网的时间同步,结合了动态分簇算法,均衡了整个网络的功耗,克服了TPSN算法中参考节点负担过重,而导致某些节点过早的死亡,实验结果表明,新的同步算法有效的提高了整个网络的生存时间与同步精度。
A Dynamic Clustering Time Synchronization (DCTS) algorithm is proposed. Firstly, according to the characteristics of wireless ranging network, the amount of transmitted data is small and the cluster head node does not need large data fusion, the LEACH clustering routing algorithm is improved. GLEACH clustering routing algorithm, and the use of GLEACH clustering routing algorithm to the entire network is divided into different clusters, with the base station and cluster head node as a reference node, using similar to the TPSN two-way synchronization mechanism, step by step synchronization, the whole network to achieve time synchronization , Combined with dynamic clustering algorithm to balance the power consumption of the entire network to overcome the overburdened reference nodes in the TPSN algorithm, leading to premature death of some nodes, the experimental results show that the new synchronization algorithm effectively improves the entire Network survival time and synchronization accuracy.
