A Cross-Layer Solution for Ultrawideband Based Wireless Video Sensor Networks
Abstract—A cross-layer communication protocol called VSNModule is introduced for Wireless Video Sensor Networks based on UltraWideBand (UWB) radio technology at the physical layer. The core of our solution is a distributed path reservation scheme which routes video traffic from sources (sensors) to a sink. The path establishment takes into account the specific requirements of video flows such as bandwidth, end-to-end delay and jitter, as well as the current status of the traversed devices such as the available bandwidth, the energy consumption, and the quality of the wireless channels. Simulation experiments are carried out and the performance of the VSN-Module is evaluated in terms of maximum end-to-end delivery delay, maximum delay jitter, and power consumption, under different video flow requirements.
