Abstract
Ultra-wideband (UWB) technology is an excellent candidate for supporting wireless personal area networks (WPANs) because of its wide bandwidth, low transmission power, low complexity and multipath immunity. We study density-aware exclusive region (ER)-based scheduling for a nonuniform UWB-WPAN. Using a generalized radius for the ER based on statistical topology, we propose a scheduling scheme that uses a radius for the ER that varies according to the density information around the destination in the nonuniform network. Computer simulations show that (i) our approach to the radius of the generalized ER provides better scheduling performance than the radius solution of the conventional work [3] and (ii) scheduling that is based on an adaptive ER radius can always outperform both the fixed ER-based scheme and the TDMA scheme with respect to network throughput.
