A First Look at Wired Sensor Networks for Video Surveillance Systems

Sensor networks are a major new area of research. Some sensor applications, such as video surveillance, will need to be tethered for reasons of bandwidth and power requirements. To support ad hoc, economical installation of video cameras there is a need for new shared-medium protocols. IEEE 1394b FireWire is investigated as a near-future candidate for a shared-medium wired sensor network (WSN). Simulation results show that FireWire can transport packetized video with low delay. In the future, WSN nodes will be capable of store-and-forward and of acting as routers and caches for arbitrary topologies. New routing protocols for attribute and location routing will be needed. We investigate a new hybrid routing scheme that uses distributed location servers to minimize broadcasting. Source routing is used as the packet forwarding mechanism. The distributed location servers contain knowledge of sensor locations and source routes between sensors and other nodes.
