Sažetak
Wireless Sensor Networks (WSNs) have received significant attention in recent years and have found a wide range of applications, including structural and environmental monitoring, mobile health, home automation, Internet of Things and others. As these systems are generally battery- operated, major research efforts focus on reducing power consumption, especially for communication, as the radio transceiver is one of the most power- hungry components of a WSN. Moreover, with the advent of energy-neutral systems, the emphasis has shifted towards research in micro-Watt (or even nano-Watt) communication protocols or systems. A significant number of wake-up radio receiver architectures have been proposed to reduce the communication power of WSN nodes. In this work we present an optimized ultra-low power (nano- Watt) wake-up receiver for use in WSNs, designed with low-cost off-the-shelf components. The wake-up receiver achieves power consumption of 152 nW (with -32 dBm sensitivity), sensitivity up to -55 dBm (with maximum power of 1, 2 μW), latency from 8 μs, tunable frequency and short commands communication. In addition, a low power solution which includes addressing capability directly in the wake-up receiver is proposed. Experimental results and simulations demonstrate low power consumption, functionality and benefits of the design optimization compared to other solutions, as well as the benefits of addressing to reduce false positive outcomes.
