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) 无线通信设备的特点是带宽超过 500 MHz，可以在 10 m 的距离内实现超过 100 Mbps 的数据速率。这有可能开辟广阔的市场，首先是高速个域网 (PAN)。然而，在 UWB 网络被广泛接受之前，必须回答一系列有关 UWB 网络性能的重要问题。出于这一动机，该项目的目标是利用理论分析和仿真支持，为 UWB 设计高效的网络算法和协议，以最大限度地提高网络容量。该项目正在研究 UWB 无线网络（包括自组织网络）中的联合功率自适应、调度和路由问题。所使用的方法是获得最佳的集中式算法作为其解决方案，然后对解决方案进行彻底分析，然后将解决方案转换为实际 UWB 物理层和 MAC 层的分散式协议。该项目将通过科学出版物为UWB网络协议设计提供指导，加速UWB网络市场的发展。最佳物理层技术（例如功率自适应）对网络的影响将被量化，以补充当前的启发式方法。严格的跨层优化技术的开发和“网络分层”数学概念的探索将被纳入 PI 的通信课程中，从而在通信和网络之间提供有趣的链接。将利用 PI 的无线教育实验室，通过 MAC 协议实验来鼓励本科生参与该项目。
