Welcome to CUHK AIoT Lab! Our research lies at the interface between systems, embedded AI, data/information processing algorithms, and domain sciences, with a focus on interdisciplinary applications in health, environment, and energy. Our lab develops new technologies at the frontier of mobile health, Cyber-Physical Systems (CPS), Internet of Things (IoT), wireless networks, security and privacy. Several mobile health technologies developed in our lab have been commercialized and used by thousands of users. Prof. Xing led the development and field deployment of several large-scale cyber physical systems, including 20+ seismic monitoring systems on two live volcanoes in South America. He has been awarded 10 NSF grants, including 4 large multi-institute grants from major NSF interdisciplinary programs (Smart and Connected Health, Cyber Physical Systems, Cyber-Innovation for Sustainability Science and Engineering, and Cyber-Enabled Discovery and Innovation). Prof. Xing has served as the Steering Committee member, General Chair, and TPC Chair of several international conferences including IPSN – IEEE/ACM’s premier conference on information processing in sensor systems.

Research Projects

💡 Smart Mobile Health Systems: A key global challenge today is to deliver high quality yet economically efficient healthcare solutions. The prominence of mobile technologies holds the promise of fundamentally transforming today’s reactive, hospital-centered healthcare practice to proactive, individualized care, and shifting the focus from disease to wellbeing. Our work on mobile health focuses on 1) building novel mobile systems that can monitor holistic health data ranging from biological rhythms (heart/respiration rate, sleep quality etc.), daily activities (work, family routine, exercise, etc.), to social interactions in dynamic, challenging environments, 2) transforming health data to behavioral, psychological, and physiological models using novel sensing and data analytics techniques, and 3) developing motivational feedback systems to empower individuals to improve lifestyles and participate in their own health treatment.

Biological rhythm monitoring and regulation. Biological rhythms, including sleep/wakefulness cycle, heartbeat, and respiration, play a central role in maintaining our daily productivity and wellbeing. We develop novel systems that leverage off-the-shelf smartphones and wearables for long-term, continuous, accurate biological rhythm monitoring and regulation.
Stacks Image 93
Integrated mobile sensing and motivational feedback for family and community wellness. We are developing integrated activity routine sensing and feedback systems that empower families and communities to actively engage in tackling chronic diseases such as obesity, depression, diabetes, and dementia. Our system can autonomously log family/community routines in an unobtrusive, privacy-preserving manner, and motivate members to work together toward improved wellness.

Unobtrusive sleep quality profiling. Over 40 million people in the US suffer from long-term sleep disorders. We developed mobile systems for unobtrusive, in-place sleep monitoring. We aim to go beyond the basic quantification of sleep quality to the provision of tailored behavioral feedback in the form of data-driven and clinician-approved actionable recommendations for improving sleep.

💡 Cyber-physical Systems and Internet of Things. CPS and IoT interact with the physical world by tightly integrating sensing, actuation, computation, and physical objects. As a key enabling technology for many critical domains such as environment, smart cities, transportation, and smart grids, CPS and IoT have been recognized as a top national research priority in several US presidential reports. Many CPS and IoT systems must process large volume of data from dynamic environments under tight energy and real-time constraints. We have developed new systems and computing paradigms for such data-intensive CPS/IoT applications. My group has developed new systems and computing paradigms for such data-intensive CPS applications.

Real-time 4D volcano tomography. We developed new wireless sensor systems for real-time and long-lived volcano monitoring, and deployed 20+ nodes on two live volcanoes in Ecuador and Chile. These systems can analyze seismic signals and compute real-time, full-scale three-dimensional tomography of the volcano conduit system within the network in a distributed manner.

Robotic sensor systems for aquatic monitoring. We developed an aquatic robot system that integrates an off-the-shelf smartphone and a gliding robotic fish for debris monitoring, fish tracking, and harmful algae blooms (HABs) detection. We also developed new aquatic diffusion process profiling and spatiotemporal aquatic field reconstruction algorithms.

Data center thermal/energy management. We developed a novel cyber-physical approach for thermal management in data centers, which integrate enables more efficient thermal/power management. It predicts the temperature evolution of a data center in real time, and then finds the temperature setpoints, cold air supply rates, and the speeds of server internal fans to minimize the expected total energy consumption of cooling and circulation system.

Networked Vehicular Systems: Driver Sensing and Wireless Networking. We propose a novel cross-layer wireless design approach that leverages signatures of upper-layer vehicular protocols to improve PHY and link layer performance. We also develop a system based on smartwatches and smartphones, which detects the driver's unsafe driving behaviors in a real-time manner.

CPS platforms and performance control frameworks. We develop a smartphone-based platform for data-intensive cyber-physical applications, which has been adopted in several large-scale volcano-monitoring sensor systems and aquatic robotic systems. We also proposed a unified sensing fidelity and real-time performance control framework for cyber-physical systems whose operations are subject to uncertainties from physical environments.

💡Security and Privacy for Internet of Things. Internet of Things (IoT) involves the increasing prevalence of objects and entities that are usually wirelessly connected and communicate within short distances. Our work focuses on identifying critical security and privacy vulnerabilities of and developing novel, practical counter measures for Near Field Communication (NFC), Bluetooth, and visible light communication (VLC).

Practical Bluetooth sniffing and identification systems. Bluetooth has become the de facto wireless interface for mobile and IoT devices. We developed the first practical Bluetooth traffic sniffing and identification systems, and proposed countermeasures. Our results have significant implications on IoT security, localization and tracking.

Near Field Communication (NFC) security. NFC has enjoyed drastic penetration in mobile payment, wearable devices, smart appliance, logistics, and smart objects and tags. We are among the first to systematically study the eavesdropping vulnerability of NFC, and design a hardware security system against passive eavesdropping based on wireless energy harvesting.

Secure Visible Light Communication (VLC) for IoT. VLC is a promising connectivity technology for IoT thanks to its extreme scalability and pervasive lighting infrastructure. We have developed the first practical VLC system for smartphones and IoT devices based on new 2D barcodes, formally analyzed the security of VLC systems, and proposed physical security enhancement mechanisms.

💡Wireless Coexistence in Open Radio Spectrum: Curses and Blessings. We are among the first to systematically study the issue of co-existence between Wi-Fi and ZigBee networks. We also demonstrate the significant benefits of exploiting cross-technology wireless interference. We develop new systems that utilize ZigBee radios to identify the existence of Wi-Fi networks which have been used for WiFi discovery on mobile devices and time synchronization in large ZigBee networks.
