TelosW: Enabling Ultra-Low Power Wake-On Sensor Network
Sensor networks are typically sensor or radio event driven. Exploiting this property the authors propose a novel wake-on sensor network design. In this paper, they have designed a new sensor platform called TelosW. The wake-on sensing capability of TelosW lets designated sensors wake up the microcontroller(MCU) only on occurrence of some event with pre-configurable threshold. TelosW also includes the CC1101 Wake-On Radio (WOR) hardware that performs low power listening without intervention of MCU. These all lead to a completely event driven wake-on sensor network that reduces energy consumption considerably. TelosW is also equipped with an on-board energy meter that can precisely measure in-situ energy consumption.
