|| Cyber-Physical-Social Convergence in Smart Living: Challenges and Opportunities
|| We live in an era in which our physical and personal environments are becoming increasingly intertwined and smarter due to the advent of pervasive sensing, wireless communications, computing, and actuation capabilities. Indeed our daily lives in smart cities and connected communities depend upon a wide variety of smart service systems and cyber-physical infrastructures, such as smart energy, transportation, healthcare, supply-chain, etc. Alongside, the availability of low-cost wireless sensor networks (WSNs), Internet of Things (IoTs), and rich mobile devices (e.g., smartphones) are also empowering humans with fine-grained information and opinion collection through crowdsensing about events of interest, thus resulting in actionable inferences and decisions. This synergy has led to cyber-physical-social convergence with human in the loop that exhibits complex interactions, inter-dependencies and adaptations between engineered/natural systems and users with a goal to improve quality of life experience what we call smart living. However, the main challenges are posed by the scale, heterogeneity, big data, and resource limitations (e.g., energy) in context recognition and situation awareness using sensors, IoTs and CPS networks. This talk will highlight unique research issues and challenges in smart living and CPS systems, followed by novel solutions for energy-efficient data gathering and fusion, lifetime optimization and security in WSNs, and trade-off between energy and information quality in multi-modal context recognition. Our research is based on online and randomized algorithms, graph theory, game theory, trust model, and information theory. Case studies and experimental results will be presented for energy efficient homes and smart healthcare applications. The talk will be concluded with directions for future research.
