Basagni to Give IFIP Wireless Days 2016 Keynote Speech
ECE Associate Professor Stefano Basagni will be presenting the keynote speech at the IFIP Wireless Days 2016 in Toulouse, France on March 24, 2016. The speech will be on "Beyond Duty Cycling: How Wake-up Radio Technology and Semantic Addressing Enable Very Long-lived Wireless Sensing Systems (Finally!)"
Abstract: 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.
