Abstract

Time synchronization is a critical middleware service of wireless sensor networks. Since the performance of time synchronization algorithm is greatly influenced by many factors, benchmark for evaluating time synchronization algorithm is not only difficult but also urgently needed. Software simulation is a good solution especially in the comparison between similar algorithms. In this paper, we presented a time synchronization simulator, Simsync, for wireless sensor networks. Simsync models the distribution of packet delay and the frequency of crystal oscillator as Gaussian. Based on it, we realized reference broadcast synchronization algorithm (RBS) and broadcast time synchronization algorithm (BTS) in 3 different scenarios. Simulated results are compared with the analytic results to advocate its effectiveness
