We live in an era in which our physical and personal spaces are becoming
increasingly intertwined and smarter due to sensing, communications,
computing, and actuation technologies. Our daily life in smart spaces depend
on a wide variety of cyber-physical infrastructures, such as smart energy,
transportation, healthcare, and so on. Alongside, IoTs and smartphones are
empowering humans with fine-grained information and opinion collection
through crowdsensing about events of interest, resulting in actionable
inferences and decisions. This synergy led to cyber-physical-social (CPS)
convergence with human in the loop with a goal to improve quality of life and
experience in what we call smart living. However, the main challenges are
posed by the scale, heterogeneity, big data, and resource limitation in context
recognition and situation awareness in interdependent CPS networks. This
talk will highlight unique research challenges in smart living, followed by a
summary of novel frameworks and models for energy-efficient data gathering,
fusion, coverage and connectivity, security, trustworthiness, and information
quality in multi-modal context recognition. Case studies and experimental
results from smart grid and smart healthcare applications will be presented.
The talk will be concluded with directions for future research.
