Ultra-wideband (UWB) wireless communication devices, characterized by bandwidths over 500 MHz, can achieve data rates above 100 Mbps over distances of 10 m. This has the potential to open up vast markets, beginning with high-speed personal area networks (PAN). However, a host of important questions must be answered about the performance of UWB networks prior to their widespread acceptance. With this motivation, the aim of the project is to design efficient networking algorithms and protocols for UWB, using theoretical analysis, supported by simulations, to maximize network capacity. The project is investigating the problem of joint power adaptation, scheduling and routing in UWB wireless networks, including ad hoc networks. The methodology used is to obtain an optimal centralized algorithm as its solution, followed by a thorough analysis of the solution, and then the translation of the solution to decentralized protocols for practical UWB physical and MAC layers. The project will provide guidance, through scientific publications, for UWB network protocol design, to speed up the development of the UWB network market. The impact of optimal physical layer techniques, such as power adaptation, on networking will be quantified, complementing the current heuristic approach. The development of rigorous cross layer optimization techniques and the exploration of a mathematical notion of 'network layering' will be incorporated into the PI's communication courses, providing interesting links between communications and networking. Undergraduate participation in the project will be encouraged through experiments on MAC protocols, using the PI's wireless educational laboratory.

超宽带（UWB）无线通信设备的特征在于超过500 MHz的带宽，可以在10 m的距离上实现超过100 Mbps的数据速率。这有可能打开巨大的市场，首先是高速个人区域网络（PAN）。然而，在UWB网络被广泛接受之前，必须回答关于UWB网络性能的许多重要问题。有了这个动机，该项目的目的是设计有效的网络算法和协议的UWB，使用理论分析，仿真支持，以最大限度地提高网络容量。本计画主要研究超宽频无线网路中的联合功率调整、排程与路由问题。所使用的方法是获得一个最佳的集中式算法作为其解决方案，其次是一个彻底的分析的解决方案，然后翻译的解决方案，以分散的协议，为实际的UWB物理和MAC层。该项目将通过科学出版物，为UWB网络协议设计提供指导，加快UWB网络市场的发展。最佳的物理层技术，如电源适配，对网络的影响将被量化，补充目前的启发式方法。严格的跨层优化技术的发展和“网络分层”的数学概念的探索将被纳入PI的通信课程，提供通信和网络之间有趣的联系。通过使用PI的无线教育实验室进行MAC协议实验，鼓励本科生参与该项目。
