| 摘 要： | 传统传感器网络的时间同步方案不适合中高速传感器网络对数据融合和大数据量传输的需要。在固定网络拓扑的结构下,存在邻居节点同步误差较大的问题。同时,全网同步并不适合中高速传感器网络中数据处理周期较长的情况。提出了一种事件触发式、局部同步的中高速传感器网络同步机制及其对应的同步路由算法,解决了邻居节点问题。仿真结果证明,该算法降低了网络中事件区域的同步开销,减小了兴趣节点间的同步误差。

| Abstract: | The traditional time synchronization in WSN does not fit the special needs of Medium and High Rate WSN(MHWSN) ,in which data fusion and data transmission are in large scale. In the case of fixed topology, there is the problem that the synchronization errors between neighbor nodes are relatively large. At the same time, the data processing of MHWSN takes more time than the WSN,so the global synchronization mechanism is not suitable. An event triggered synchronization mechanism was presented in this paper. A local routing algorithm for synchronization was designed to solve the neighbors' synchronization problem. The simulation results show that the proposed synchronization mechanism reduces the cost of synchronizing in the event area, and the synchronization error between interest nodes is lowered. |
