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500 MHz，在10米的距离内可以达到100 Mbps以上的数据速率。这具有打开广阔市场的潜力，首先是高速个人区域网(PAN)。然而，在广泛接受UWB网络之前，必须回答许多关于UWB网络性能的重要问题。在这种动机下，该项目的目标是利用理论分析和仿真支持，为UWB设计高效的组网算法和协议，以最大化网络容量。该项目正在研究UWB无线网络中的联合功率自适应、调度和路由问题，其中包括自组织网络。所采用的方法是获得一个最优的集中式算法作为其解决方案，然后对该解决方案进行深入的分析，然后将该解决方案转化为适用于实际UWB物理层和MAC层的分散协议。该项目将通过科学出版物为UWB网络协议设计提供指导，以加快UWB网络市场的发展。电源适配等最佳物理层技术对网络的影响将被量化，作为对当前启发式方法的补充。严格的跨层优化技术的发展和对“网络分层”的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。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。

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.
