Wakeup radios (also referred to as event-driven radios) is a paradigm for low-cost, low-energy identification radios to assist the main radio for continuous channel monitoring without sacrificing the latency requirements. Wakeup radios show the potential to extend considerably the life-time of the main radios. In this paper, we present the design, and measurement results of an ultra low-power wakeup...
Machine-to-Machine (M2M) technologies allow network-to-device communications. M2M covers a wide scope of technologies including sensing and wireless networking protocols. Hazard monitoring applications based M2M such as monitoring using wireless sensor networks (WSNs) are challenged by real-time and interference-aware requirements. The designed communication mechanisms need to guarantee efficient...
Wake-up radio technology is a means to improve energy efficiency in low-power wireless sensor networks. In such radios, low-power low-complexity designs are considered, often based on narrow-band transmission, simple modulation techniques, noncoherent detection and matched filter receivers. In order to improve the performance of wake-up radios in interference limited scenarios, while keeping the power...
Channel capacity and node energy represent resources and constraints in designing efficient routing schemes for Wireless Sensor Networks(WSNs). To delivery more data, a higher rate is desirable, which however consumes more energy and may demand more bandwidth. Hence, data transmission in WSNs should take into account both limited capacity and constrained energy. In this paper, we propose an utility-based...
