Rapid advancements in embedded systems, sensors and wireless communication technologies have led to the development of wireless sensor networks (WSNs) including video sensors. Such networks have attractive applications in civilian, military, industry, and government sectors as they can effectively act as the human-physical world interface in future digital world through sensing and actuating. However, the inherent characteristics of WSNs typified by extremely scarce resources (bandwidth, CPU, memory and battery power), high degree of uncertainty, and distributed operations and control pose significant challenges in providing the desired information quality, assurance, reliability, security and privacy. This is particularly important for mission critical applications such as health care and pervasive security.

This talk will examine uncertainty-driven unique research challenges and some novel solutions for information-intensive (multimedia) wireless sensor networks in the areas of data quality, aggregation/fusion, dissemination, routing, coverage and connectivity, trust, security and privacy. The talk will be concluded with future directions of research in wireless sensor networks.
