| Abstract(in English) | In this paper, we present an evaluation of the decrease of throughput and the increase of CPU usage resulting from high-fidelity synchronized sampling with wireless sensor networks. Sampling jitter which is caused by tasks other than sampling (ex. wireless communication) and time synchronization errors have to be minimized for high-fidelity synchronized sampling with wireless sensor networks. We proceede to research of a synchronized sampling system to minimize the uncertainty of a task's timing. Our system decreases the performance of the sensornode, because of intrupput control system and creitical section control system which minimize the uncertainty of a task's timing. The result of implementation and evaluation in TinyOS/IRIS show sampling jitter to be is about 2.2 us, decrease of communication throughput is about 18% and CPU usage of synchronized sampling is 4.0 us. |
