Abstract: Nowadays clock synchronization has become crucial in wireless sensor network (WSN), in particular for those scenarios where the common reference time is vital for applications. The existing approaches often suffer from synchronizing errors since the effect of clock granularity is overlooked. In this paper, a novel algorithm is proposed on the basis of PulseSync algorithm. Compared with PulseSync, the improvement of the presented algorithm is twofold: First, clock discreteness is abated via applying filter method. Second, for reducing the deviation of estimated clock skew through several hops, relative logical clock rate is straightly delivered. Our approach, along with the deeper analyses, is further validated with EXP5438 platform using Contiki operating system in Cooja simulator. The result illustrates that the proposed algorithm outperforms PulseSync in synchronization accuracy.

 

Keywords: Clock synchronization, WSN, Clock granularity, PulseSync.
