Beyond Duty Cycling: How Wake-up Radio Technology and Semantic Addressing Finally Enable Very Long-lived Wireless Sensing Systems
Emerging wake-up radio technologies have the potential to bring the performance of sensing systems and of the Internet of Things to the levels of low latency and very low energy consumption required to enable critical new applications. In this talk we provide advancements toward this goal by describing how combining the latest wake-up radio design and semantic addressing conjures to provide wireless sensor systems that can last decades. In particular, we first describe the design and prototyping of a wake-up receiver (WRx) and its integration to a wireless sensor node. Our WRx features very low power consumption (<1.3uW), high sensitivity (up to -55dBm), fast reactivity (wake-up time of 130us), and semantic addressing, a key enabler of new high performance protocols. We then present ALBA-WUR, a cross-layer solution for data gathering in sensing systems that redesigns a previous leading protocol, ALBA-R, extending it to exploit the features of our WRx. We finally show results of the simulation-based performance evaluation of ALBA-WUR, quantifying the gain produced by the use of WRx with semantic addressing: Short delays, up to five orders of magnitude energy savings and lifetimes that are decades longer than those obtained by ALBA-R in sensing systems with duty cycling.

Biografia
Stefano Basagni holds a Ph.D. in electrical engineering from the University of Texas at Dallas (December 2001) and a Ph.D. in computer science from the University of Milano, Italy (May 1998). He received his B.Sc. degree in computer science from the University of Pisa, Italy, in 1991. Since Winter 2002 he is an associate professor at the Department of Electrical and Computer Engineering at Northeastern University, in Boston, MA.
Dr. Basagni's current research interests concern research and implementation aspects of mobile networks and wireless communications systems, wireless sensor networking (underwater and terrestrial), definition and performance evaluation of network protocols and theoretical and practical aspects of distributed algorithms.
Dr. Basagni has published over seven dozens of highly cited, refereed technical papers and book chapters. His h-index is currently 28. He is also co-editor of three books.
Dr. Basagni served as a guest editor of multiple international ACM/IEEE, Wiley and Elsevier journals. He has been the TPC co-chair of international conferences such as ACM Dial M for Mobility (2004), Med Hoc Net (2006), IEEE SECON (2010), IEEE Globecom (AHSN Symposium, 2012), IEEE MASS (2012), IEEE WiMob 2013 and ICNC 2015.
Dr. Basagni serves as a member of the editorial board, the organizing committee and of the technical program committee of ACM and IEEE journals and international conferences. He is a senior member of the ACM (including the ACM SIGMOBILE), a senior member of the IEEE (Computer and Communications societies), a member of ASEE (American Society for Engineering Education) and of CUR(Council for Undergraduate Education).
