In many wireless sensor network scenarios, battery-powered nodes must operate for years, which necessitates the need for advanced power management of the radio. In this paper we pursue the idea of using a second, ultra low-power radio that can be used to trigger a remote interrupt, so that a receiver can fire up its primary radio to engage in efficient high-speed communication with the sender. Wakeup radio avoids the complex bookkeeping associated with energy-efficient MAC protocols, but at the… CONTINUE READING
