Visual Sensor Networks is a valuable technology to support many applications in different areas, such as: environmental and habitat monitoring, surveillance, smart homes for elderly care and kinder garden, smart meeting rooms including teleconferencing and virtual studios, virtual reality with telepresense systems, disaster management and so on. Participating nodes in these networks is inherently resource constrained, since they have limited processing capabilities, storage, communication speeds, bandwidth, and mainly they have very limited power supply. The primary difference between Visual Sensor Networks and Wireless Sensor Network is Visual Sensors can cover larger fields of view and extract more substantial information than simpler sensors. Visual Sensor Networks includes visual processing and communication and hence consumes more energy than Wireless Sensor Network.
