Abstract

<abstract abstract-type="main" id="wcm1144-abs-0001"> <title>ABSTRACT</title> <p>Reliability is a crucial aspect of time synchronization for industrial wireless applications in wireless sensor networks. Existing time synchronization algorithms often provide good synchronization in laboratory environments; however, outdoor environments with associated radio interference influence the performance of time synchronization. In this paper, we propose a random time source protocol for industrial wireless applications in wireless sensor network synchronization. Each synchronized node randomly selects its time source for each period in order to prevent reliance on a fixed time source because this may lead to resynchronization once the source fails. We have implemented the algorithm on the SIA2420 platform using <sc>TinyOS</sc>, and the results show the reliability of our protocol. Copyright © 2011 John Wiley &amp; Sons, Ltd.</p> </abstract>
