This letter presents three different strategies for waking up wireless sensor network (WSN) motes via radio frequency identification (RFID). Based on our prior work on the design of augmented ultrahigh-frequency RFID tags and ultrasensitive RF energy harvesters, the proposed solutions significantly outperform state-of-art RFID wake-up radios (both broadcast based and ID based) for WSNs. In particular, improvements up to (4.2×) and (7.8×) have been achieved in terms of wake-up range and wake-up delay, respectively.

Abstract
This letter presents three different strategies for waking up wireless sensor network (WSN) motes via radio frequency identification (RFID). Based on our prior work on the design of augmented ultrahigh-frequency RFID tags and ultrasensitive RF energy harvesters, the proposed solutions significantly outperform state-of-art RFID wake-up radios (both broadcast based and ID based) for WSNs. In particular, improvements up to (4.2×) and (7.8×) have been achieved in terms of wake-up range and wake-up delay, respectively.File in questo prodotto:
