N2 - In this paper, power allocation and scheduling issues are studied for ultra-wideband (UWB) wireless networks. An optimization problem is first formulated to jointly maximize system spectral efficiency and minimize power consumption, taking into account advantages of UWB inherent properties (such as the capacities in supporting parallel transmissions and providing accurate positioning). For UWB networks with a stringent constraint on complexity, a margin-based power allocation scheme and an exclusive region-based scheduling scheme are then proposed. The margin-based power allocation scheme utilizes each node's own position information, and the exclusive region-based scheduling scheme takes into consideration the interaction among simultaneous transmission links. Simulation results demonstrate the effectiveness of the proposed power allocation and scheduling schemes.
