RECERCAT author Cervià Caballé, Martí author Calveras Augé, Anna M. author Paradells Aspas, Josep 2021-01-01 Nowadays, several wireless communication solutions targeted at low-power devices (e.g. sensors, actuators) compete for market dominance. As a consequence, the deployment of the Internet of Things is slowed by fragmentation. However, Cross-Technology Communication (CTC) has appeared as a solution capable of bridging the 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 WuR was originally proposed to reduce radio power consumption, it provides a secondary communications channel that can be used for high-speed and bidirectional CTC. With WuRCTC, we demonstrate that WuR can lead to interoperability between non-compatible wireless devices, therefore, providing a compelling reason for the harmonization of the nascent WuR specifications. This article presents a WuR-CTC solution implemented on an heterogeneous testbed with IEEE 802.11 and IEEE 802.15.4 devices. The resulting testbed achieves reliable CTC with an effective throughput of 26.7 kbps. Moreover, the addition of WuR to the testbed devices provides energy savings, and, in a clear advantage over traditional duty-cycled solutions, allows devices to asynchronously maintain communications.Postprint (published version) http://creativecommons.org/licenses/by/3.0/es/ Open Access Attribution 3.0 Spain Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telemàtica i xarxes d'ordinadors Wireless LANs Personal area networks (Computer networks) Wireless communication systems WLAN IEEE 802.11 WPAN IEEE 802.15.4 IEEE 802.11ba wake-up radio Crosstechnology communication Energy-efficient communication Xarxes locals sense fil Wi-Fi Comunicació sense fil, Sistemes de Wake-up radio: an enabler of wireless convergence Article
