Abstract

Ultra-wideband (UWB) has great potential for wireless communications in emerging applications such as sensor networks. This paper studies the following fundamental problems for UWB-based sensor networks. For a given network instance , what is the maximum data rate (network capacity) that can be received at the base-station (i.e.,sink node)? What is the network capacity bound among arbitrary network instances? We show that these problems can be cast into a cross-layer formulation with joint consideration of routing, scheduling,power control, and rate assignment. For a given network instance ,we find a closed-form network capacity as well as corresponding optimal routing,scheduling,power control,and rate assignment. We also find a network capacity bound among arbitrary network instances.
