Resource management for adaptive networks: fundamental limits, tradeoffs and enabling algorithms

本研究的目标是开发框架、模型、工具和算法，以支持大型(广域和多用户)网络的设计和部署，这些网络能够适应不同的通道条件、应用的异质性和移动性。我们的研究将集中在需要解决的关键领域，即网络中的多跳无线体系结构和覆盖。研究将涉及网络的大多数层，即应用层、网络层、链路层、传输层和物理层，因为通过统一处理这些问题，我们可以希望利用无线和有线基础设施来提供所需的性能。在这种情况下，自适应是必要的，因为覆盖和无线链路意味着信道不断变化。移动性增加了适应需求的另一个维度，因为它意味着网络拓扑和链路将不断变化。在每种情况下，对网络算法的影响都是不同的。我们的目标是开发稳健和自适应的资源分配、控制和路由算法。除了提供自适应资源分配和控制的模型、工具、算法和原则外，我们的研究还旨在提供对多跳无线网络和覆盖对底层基础设施的影响的基本了解。这项研究将具有强大的科学意义，同时也是HQP的重要组成部分。我们得到了加拿大该领域最重要的两家技术领先者的坚定承诺。它们的互动将促进专门知识的转让，并有助于完善由于技术和应用的迅速进步而至关重要的研究方向。

The goal of this research is to develop frameworks, models, tools, and algorithms to enable the design and deployment of large (wide-area and many users) networks that are capable of adapting to varying channel conditions, heterogeniety of applications, and mobility. Our research will focus on the critical areas that need to be addressed, namely, multi-hop wireless architectures and overlays in networks.The research will involve most layers of the network, namely, the applications, network, link, transport, and physical layers since it is by treating these problems in a unified way that we can hope to exploit the wireless and wireline infrastructure to deliver the requisite performance. Adaptation is a necessity in such a context because of overlays and wireless links which mean that the channels are constantly varying. Mobility adds another dimension to the need for adaptation since it means that the network topology and links will constantly change. In each case the impact on network algorithms is different. The goal is to develop robust and adaptive algorithms for resource allocation, control, and routing.Besides providing models, tools, algorithms, and principles for adaptive resource allocation and control, our research aims at providing a fundamental understanding of multi-hop wireless networks and the impact of overlays on the underlying infrastructure. The research will have a strong scientific import as well as a substantial HQP component. We have a strong commitment from two of Canada's most important technology leaders in the field. Their interaction will facilitate the transfer of the knowhow as well as help in refining the research directions that is essential because of rapid advances in technology and applications.
