Wake-Up Radio: An Enabler of Wireless Convergence

Nowadays, several wireless communication solutions targeted at low-power devices (e.g. sensors, actuators) compete for market dominance. As a consequence, the deployment of Internet Things is slowed by fragmentation. However, Cross-Technology Communication (CTC) has appeared as solution capable bridging compatibility gap between non-interoperable devices. In this way, we propose using Wake-up Radio (WuR) to achieve high rate bidirectional CTC, introducing WuR assisted CTC (WuR-CTC). Although was originally proposed reduce radio power consumption, it provides secondary communications channel that can be used high-speed and CTC. With WuR-CTC, demonstrate lead interoperability non-compatible devices, therefore, providing compelling reason harmonization nascent specifications. This article presents WuR-CTC implemented on an heterogeneous testbed with IEEE 802.11 802.15.4 The resulting achieves reliable effective throughput 26.7 kbps. Moreover, addition energy savings, and, in clear advantage over traditional duty-cycled solutions, allows asynchronously maintain communications.
