Abstract
The wireless sensor network (WSN) node is required to operate for several months with the limited system resource such as memory and power. A general WSN node operates in the active state during less than 1% of the several-month lifetime and waits an event in the inactive state during 99% of the same lifetime. This paper suggests a power adjust dual priority scheduler (PA-DPS) for low-power, which has a structure to meet the requirements for the WSN by estimating power consumption in the WSN node. PA-DPS has been designed based on an event-driven approach and is based on the dual-priority scheduling structure, which has been conventionally suggested in the real-time system field. From experimental results, PA-DPS reduced the inactive mode current up to 40% under the 1% duty cycle.
