NeTS-NBD: Algorithms for ultra-wideband wireless networks

超宽带（UWB）无线通信设备的特点是带宽超过500mhz，可以在10米的距离上实现100 Mbps以上的数据速率。从高速个人区域网络（PAN）开始，这有可能打开广阔的市场。然而，在UWB网络被广泛接受之前，必须回答关于其性能的许多重要问题。基于这一动机，该项目的目标是为UWB设计有效的网络算法和协议，利用理论分析，辅以仿真，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）中的联合功率适应、调度和路由问题。所使用的方法是获得一个最优的集中式算法作为其解决方案，然后对解决方案进行彻底的分析，然后将解决方案转换为实际UWB物理层和MAC层的分散协议。该项目将通过科学出版物为超宽带网络协议设计提供指导，以加快超宽带网络市场的发展。最优物理层技术（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发展和对“网络分层”数学概念的探索将被纳入PI的通信课程，在通信和网络之间提供有趣的联系。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。

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.
