There is growing interest in employing ultra-wideband (UWB) communication systems at the physical layer for multihop wireless networks. Recent efforts show that networking problems involving UWB systems should follow a cross-layer approach with consideration at multiple layers. Due to the nonlinear nature of the optimization problem, there are very limited theoretical results for this important problem...
In this paper, we consider a UWB-based ad hoc network and study how to maximize data rate utility for a group of communication sessions. We formulate the data rate utility problem into a nonlinear programming (NLP) problem through a cross-layer approach by taking into consideration of scheduling and power control at link layer and routing at network layer. The main contribution of this paper is the...
