Abstract
Cognitive Ultra-Wideband (UWB) network is the UWB network with the ability of sensing spectrum, detecting the available spectrum holes in primary system, and communicate in the detected spectrum holes. Based on the precise position capability of UWB technology and the spectrum sensing information, local clusters are constructed by neighbor nodes which operated in the same spectrum channel, and the entire network is interconnected by the clusters through bridge gateway nodes. Furthermore, a spectrum-aware routing scheme is provided for clustered cognitive UWB network, which including the process of routing discovery and repairing. The unique feature of this routing scheme is its ability of intelligent adaptation to the change of network and available spectrum resource. Simulation proved the performance of spectrum-aware routing in dynamic spectrum environment is better than traditional routing scheme with fixed spectrum allocation.
