Abstract

Time synchronization is a critical piece of infrastructure in any wireless sensor network. Time synchronizing nodes are nodes which are responsible for propagating time in the network. Other nodes in the network synchronize themselves with respect to the synchronizing nodes. For various reasons, it is desirable that the number of such nodes is minimized. In this paper, we consider selection of time synchronizing nodes for two protocols viz. a protocol that helps propagate absolute time in the network and another protocol that provides nodes with local relative timescales. We show that the problem of selection of minimum number of time synchronizing nodes for the two protocols is NP-Complete. We then consider selecting time synchronizing nodes for one of the two protocols, Reference Broadcast Synchronization (RBS) protocol, present simulation results. We further present a fault tolerant selection of synchronizing nodes for RBS.
无线传感器网络时间同步节点的选择
在任何无线传感器网络中,时间同步都是基础设施的关键部分。时间同步节点是网络中负责时间传播的节点。网络中的其他节点相对于同步节点进行自身同步。出于各种原因,我们希望最小化此类节点的数量。在本文中,我们考虑了两种协议的时间同步节点的选择,一种是帮助在网络中传播绝对时间的协议,另一种是为节点提供本地相对时间尺度的协议。我们证明了两种协议的最小时间同步节点数选择问题是np完全的。然后考虑为参考广播同步(RBS)协议选择时间同步节点,并给出仿真结果。我们进一步提出了RBS同步节点的容错选择。
