Cyber-Physical and Networked Sensor Systems: Challenges and Opportunities

The University of Texas at Arlington, USA




Rapid advancements in embedded systems, sensors and wireless
communication technologies have led to the development of cyber-physical systems, pervasive computing and smart environments with important applications such as smart grids, health care and security. Wireless sensor networks play significant role in building such systems as they can effectively act as the human-physical interface with the digital world through sensing, communication, computing and control or actuation.

However,the inherent characteristics of wireless sensor networks, typified by  resource constraints, high degree of uncertainty, heterogeneity and distributed control pose significant challenges.


This talk presents a novel framework for multi-modal context recognition from low-level sensor streaming data, context-aware data fusion, and situation-aware decision making with improved information accuracy and context inference quality. The underlying approach is based on dynamic Bayesian model, information theoretic reasoning, and energy-accuracy trade-off analysis. The talk is concluded with open issues and future directions of research.
