IEEE WiSense: 2nd International Workshop on Pervasive Wireless Sensing and Edge Computing


Scope

Wireless sensing has recently attracted a great deal of attention thanks to its non-invasive and sensor-free nature. Contrary to traditional sensor-based and wearable sensing, wireless sensing does not need any sensors, but leverages the modifications induced on the wireless channel by objects and people to infer information about their position and movement within a physical environment. This leads to an unobtrusive system that can be integrated with nowadays transmission technology. Moreover, if operated, e.g., at sub-6GHz frequencies, wireless signals propagate through walls, allowing sensing to be performed even in non-line-of sight (NLOS) scenarios with a subsequent increase in the sensing coverage over camera-based systems. Different types of wireless signals have been employed for sensing including WiFi, RFID, mmWave, UWB, and acoustic signals. As wireless signals bounce off of physical objects within the environment such as static objects like walls or furniture, as well as any humans in the environment, their characteristics (e.g., amplitude, phase) change uniquely. This then provides an opportunity to sense the environment and obtain contextual information (e.g., recognizing the motion) through a finegrained analysis of signal variations. Wireless sensing has been considered in various applications including but not limited to localization, human activity and gesture recognition, gait estimation, fall detection, respiration monitoring, crowd counting, etc.

Deploying the wireless sensing systems on edge devices is also important, to reduce their costs and make them scalable. However, this comes with several challenges due to the constrained resources (e.g., memory, computation power, energy) of edge nodes. Accordingly, in this workshop we also look for solutions that develop novel, lightweight and cost-efficient techniques that can run at the network edge, providing means to train and run machine learning models in an energy efficient manner, both according to centralized and distributed training paradigms. We are also interested in the characterization of energetic aspects on currently available edge computing technology, including but not limited to empirical energy models.

Topics

The objective of this workshop is to bring together the research community utilizing different types of wireless signals for sensing purposes, and the community dealing with computing for embedded and energy efficient systems, and have them benefit from each other's findings. The workshop will also serve as a discussion platform about the standardization and industrial implications of wireless sensing and edge computing, by also targeting potential privacy issues. Toward these goals, the workshop will span topics including, but not limited to:

  • Human activity, gesture recognition, health, and emotion sensing
  • User identification and authentication
  • Occupancy monitoring and counting
  • Localization and navigation via passive wireless sensing
  • Privacy and security issues and their prevention
  • Adversarial sensing and intrusion detection
  • Optimized machine learning algorithms for wireless sensing systems
  • Real-time wireless sensing at the network edge
  • Learning techniques and architectures for edge computing systems
  • Federated and distributed learning for energy constrained edge devices
  • Implementation of machine and deep learning algorithms on embedded and energy constrained devices
  • Energy assessment and characterization of energy constrained edge devices for both model training and inference
  • Detection of anomalies into energy consumption patterns of edge devices
  • Novel energy efficient implementations of signal processing techniques for wireless sensing systems
  • Applications of pervasive wireless sensing (agriculture, health, material identification)
  • Industrial developments and plug-n-play solutions

      Title: Wireless AI: A New Sixth Sense to Deciphering our World

      Abstract: With more and more bandwidth readily available for the next generation of wireless applications, many intelligent products/services by leveraging the ambient radio waves unimaginable before are now possible. What impact will it bring to our lives? Many may wonder or even speculate if it is science fiction or real? In this talk, we will show that with more bandwidth, one can see many multi-paths, which can serve as hundreds of virtual sensors around us that can be readily leveraged as new degrees of freedom for our use (but we never realized that before!). We discovered for the first time that the time-reversal focusing spot is not a point but exhibiting a stationary power distribution of Bessel function which enabled accurate/reliable speed estimation under nonline- of-sight, severe multipath conditions, uncovering a new physical principle ideal for indoor applications. Together with the use of machine learning, a revolutionary wireless AI platform can be built to enable many IoT applications that have been dreamed for a long time but have never been possibly achieved. Such a technology forms the core of a wireless sensing AI platform that can be applied to many device-free, nonobtrusive applications. We will show the world’s first ever centimeter-accuracy wireless indoor positioning systems that can offer indoor tracking without any costly infrastructure, home/office monitoring and security, radio human biometrics, vital signs detection, sleep monitoring, gait recognition, and fall detection, without any wearable but sorely relying on ubiquitous commodity Wi-Fi. In essence, now and in the future, it is the wireless sensing that will forever change Wi-Fi as we know it today, as well as future 5G/6G systems, allowing us to decipher our surrounding world with a new “sixth sense”. Some products/services of Origin have been deployed worldwide and will be demonstrated to illustrate how such a fundamental discovery can make the world a better place.
