This paper addresses the problem of sampling jitter on a wireless sensor network for earthquake monitoring. Since the earthquake monitoring has many data-sensitive applications such as structural health monitoring and seismology, a wireless sensor network must precisely capture earthquake phenomena. However, the precise earthquake capturing is difficult on wireless sensor networks because sampling error increases due to its distributed manner and scheduling delay. We mitigate the difficulty with a synchronized sampling mechanism with time slotted task scheduling. We analyzed the sampling jitter with a logic analyzer, and evaluated the measurement error with a shaking table experiment. The results show every sensor node can synchronously sample earthquake with up to 3.4~us jitter in a single-hop wireless network, and the jitter does not practically affect measurement quality. |
