No.8（2013）20.Development of low power protocol based on remote sensing conditions

Masashi Nakamura, Yuji Takeda

  Intermittent operation is the general power saving method in a wireless sensing network, and we propose a Group Control Method (GCM) to reduce the power-intensive data transmission time. Noting that the sensor value does not change significantly in the sensing of environment measurements, then by grouping together terminals showing the same trends, power consumption can be controlled by setting a normal sleep cycle to groups with a lot of battery life remaining and a long sleep cycle to groups with little battery life remaining. This research experimentally evaluated algorithms implemented in a real device, as well as in a simulation, and verified its effectiveness. The results of each evaluation verified the power-saving effect of this technique.
