Analysis on Range Enhancing Energy Harvester (REACH) mote passive wake-up radios for wireless networks

Abstract

Today, the wireless sensor networks are used increasingly in many applications fields and in parallel, these are used by scientific researchers to improve and accelerated the features of such networks. These designs are very challenging and are sustainable. On the above, these energy-dependent sensors are relied to run for long periods. These Sensor nodes are usually batterypowered and thus have very shorter lifetime. In this paper, we introduce a novel passive wake-up radio device called REACH (Range Enhancing Energy Harvester) Mote for a traditional sensor node, which uses the energy harvester circuit combined with an ultra-low-power pulse generator to trigger the wakeup of the mote. And this approach aims to reduce the latency without increasing energy consumption.
