Abstract

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 in civilian, military, industry, and government sectors. Wireless sensor networks (WSNs) play a significant role in such systems as they can effectively act as the human-physical world interface with the cyber world through sensing and actuation. However, inherent characteristics of WSNs typified by extremely scarce resources, high degree of uncertainty, distributed control and operations pose significant challenges in providing desired information (or context) quality, assurance, and reliability for intelligent decision making, particularly for mission critical applications like health care and security. This talk will examine uncertainty-driven unique research challenges in cyber-physical and networked sensor systems, and propose novel solutions for context fusion, coverage and connectivity, security and privacy with improved quality in WSNs in the presence of uncertainty. The talk will be concluded with open issues and future directions of research.
