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