Cross-layer Optimization in Video Sensor Networks
Video Sensor Networks (VSN) (also referred to as multimedia sensor networks or visual sensor networks) is being made possible by the integration of low-power wireless networking technologies with inexpensive CMOS cameras and microphones. Video sensor networks are self-organizing, intelligent wireless systems of embedded and resource-constrained devices deployed to retrieve, distributively process, store, correlate, and fuse multimedia streams. VSNs can potentially constitute a viable alternative to ubiquitously deployed wired surveillance systems. Once properly regulated, the availability of affordable VSN systems will enhance the ability of private citizens and law enforcement officers to observe and monitor locations and events in an unprecedented way, enabling sophisticated real-time scene analysis.
