Multi-hop relaying helps to improve the connectivity in wireless networks at the price of additional signaling overhead. In this paper, an ultra-low power wake-up radio is proposed to minimize signaling overhead and to build up energy-aware relaying route for low power applications. Protocol details are explained and energy consumption model is analyzed. The proposed scheme is compared with main radio...
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...
Wakeup radio schemes are employed to improve the energy efficiency in wireless sensor networks. In this paper, an analytical model is formulated to make a justified comparison between two different wakeup schemes, one-channel wakeup radio and two-channel wakeup radio. As the key measurement, energy efficiency is studied by taking the latency requirement as the main constraint. Moreover, the probabilities...
