| 摘 要： | 针对无线传感器网络时间同步能耗问题,提出一种能量有效的时间同步算法。该算法结合了TPSN协议和RBS协议的特点,利用无线信道的广播特性,在两个参考节点广播域里的所有节点通过监听参考节点之间的数据包交换而达到同步。并提出一种同步节点选择方法,将该同步算法扩展到多跳网络。实验结果表明,该算法在保持同步精度的同时降低了能量消耗。

| Abstract: | Considering the energy consumption of time synchronization problem in wireless sensor network,an energy efficient wireless sensor network time synchronization algorithm is presented,which combines the features of TPSN and RBS protocol.Using of the broad-cast nature of wireless channel,all the nodes in the broadcast domain of the two reference nodes can achieve synchronization by monitoring the packets exchange between the reference nodes.A synchronization node selection method is proposed,which extend the s... |
