Abstract :
Time synchronization may play a key role in wireless sensor networks to meet real-time and energy-saving requirements and improve data-fusion and multiplexing efficiency. In this paper, we introduce a clock synchronization algorithm between the base station and sensor node used in wireless check meter system. The algorithm can not only been extended more conveniently, but also less affected by environment. The algorithm is implemented in the platform of s3c2410 solidified OS of Windows CE.Net. So the most important interrupt delay contributor, ISR and IST, can not be ignored, A result for the maximum clock skew of the hardware-based synchronization is presented, which can fulfill the need of wireless sensor networks built for wireless check meter system.
