Abstract

This chapter presents the main challenges in developing complex systems built around the core concept of Video-Based Wireless Sensor Networks. It summarizes some innovative solutions proposed in scientific literature on this field. Besides discussion on various issues related to such systems, the authors focus on two crucial aspects: video data processing and data exchange. A special attention is paid to localization algorithms in case of random deployment of nodes having no specific localization hardware installed. Solutions for data exchange are presented by highlighting the data compression and communication efficiency in terms of energy saving. In the end, some open research topics related with Video-Based Wireless Sensor Networks are identified and explained.

Video-Based Wireless Sensor Networks

Combining video surveillance with wireless sensor networks brings important advantages in many fields. Resulting video-based wireless sensor networks have a large applicability especially in surveillance of critical zones to detect suspect activities. Beside obvious military applications, a lot of systems were developed for surveillance in subway and train stations, airports, hospitals, parking zones, stores, and other public places (Fernandez, 2013). Along common intrusion detection tasks, these systems can be used also to identify persons, vehicles or other kind of targets.
