摘要

由于无线传感器网络的分布式特性，时间同步在无线传感器网络中至关重要。尤其是目标跟踪应用，这是无线传感器网络中最受欢迎的应用之一，它需要高度精确的时间同步。在本文中，我们提出了自己的时间同步方案，既能满足目标跟踪应用的要求，又能最大限度地降低能耗。这是利用异构传感器网络和目标跟踪的独特特性来实现的。我们提出的方案在时间精度和能源效率方面进行了评估。正如您稍后将看到的，我们的方案可以提供比TPSN和RBS更好的时间精度和能源效率。

Energy efficient time synchronization for target tracking in heterogeneous sensor networks

Time synchronization is essential in wireless sensor networks (WSNs) due to the distributed characteristics of WSNs. Especially, target tracking applications, which are one of the most popular applications in WSNs, require highly accurate time synchronization. In this paper, we propose our own time synchronization scheme which meets the requirements of target tracking applications while minimizing the energy consumptions. This is accomplished by taking advantage of heterogeneous sensor networks (HSNs) and the unique properties of target tracking. Our proposed scheme is evaluated in terms of time accuracy and energy efficiency. As you will see later, our scheme can provide better time accuracy and energy efficiency than TPSN and RBS.
