Wireless in the ERA of IoT: From Indoor Localization to Ubiquitous Sensing

Wireless is ubiquitous and playing increasingly important roles in our everyday lives. While wireless data communication has achieved a great success, a lot of new applications were proposed in the last few years hosted on Wi-Fi and RFID infrastructures including indoor localization, gesture recognition, respiration sensing and even material identification. Several systems will be introduced in this talk. The first, ArrayTrack(NSDI ’13), is an indoor localization system hosted on Wi-Fi infrastructure to achieve​ an accuracy below 50 cm. ToneTrack(MobiCom ’15) is another Wi-Fi based system which breaks the bandwidth limit for time-based localization. TagScan(MobiCom ’17) is able to differentiate very similar liquids such as Pepsi and Coke with just commodity RFID device while the last system Restrack (​UbiComp ’18) is not only able to monitor subtle human respiration accurately without any device attached to the target but also explains the deep reason why some locations have inherently better respiration sensing capability than other locations.


Jie Xiong is an Assistant Professor in College of information and Computer Sciences at UMass Amherst. He received his Ph.D from University College London in 2015. He was awarded the prestigious Google European Doctoral Fellowship in Wireless Networking for his doctoral studies. His Ph.D thesis won the 2016 British Computer Society Distinguished Dissertation Award runner-up. He has broad research interests in building practical wireless and mobile systems that bridge the gaps between theory and reality. His recent work appeared at MobiCom, CoNEXT, UbiComp, NSDI, INFOCOM and won the CoNEXT ’14 Best Paper Award. He served MobiCom TPC in 2016, 2017 and 2018. He was an Assistant Professor in School of Information Systems at Singapore Management University from 2015 to 2017.
