An Energy-Efficient Addressing Mechanism for Wake-up Radio Systems

Abstract : Wake-up Radio receivers (WuRx) must be energy-efficient for their integration into Wireless Sensor Networks (WSNs). The most energy-hungry component is the address decoding hardware and it is generally powered by the node battery. In this paper, an addressing mechanism is proposed and the decoding process is explained in detail, on the contrary of previous works. This paper also shows the energy reduction of the address decoding stage while performed by a microcontroller, in comparison with one of the best correlator approach. The energy consumption and latency are also well investigated with real measurements, which is often omitted in previous works. Our approach is also flexible since a trade-off between energy consumption and wake-up latency is proposed. While decoding the address, the most energy-efficient mode consumes only 23.8 μA with a wake-up latency of 8.88 ms.
