摘要
本文主要研究了无线传感器网络时间同步技术,针对传感器网络能量有限的特点,提出了一种能量高效的时间同步算法EETS(Energy Efficient Time Synchronization).它采用分层成簇的策略,将网络节点划分为主次两种网络,分别使用TPSN算法和DMTS算法的思想进行时间同步,从而降低了算法复杂度,减少了通信量.仿真结果表明,与TPSN算法相比,该算法在一定程度上降低了网络能耗,有效延长了网络的生命周期.
This paper studies the wireless sensor network time synchronization technology for sensor networks with limited energy, we proposed an energy efficient time synchronization algorithm EETS （Energy Efficient Time Synchronization）. It uses a hierarchical clustering strategy, divides the network into two different subnets, respectively TPSN algorithm and idea of the DMTS algorithm for time synchronization, thereby reducing the complexity of the algorithm, reducing traffic. Simulation results show that, compared with the TPSN algorithm, this algorithm reduced the energy consumption of the network, effectively extended the network life cycle.
