NEDG: Contention-Awareness in Mesh Transport: Theory and Practice

网状网传输中的竞争感知：理论与实践多跳无线网状网正成为互联网边缘网络中越来越重要的组成部分。这些静态节点的网络提供社区联网、分布式传感和互联网接入。在每一种情况下，网状网的主要优点是易于部署和可扩展性。尽管有这些优点，网状网还没有被广泛采用。其主要原因是对此类网络的传输性能缺乏关注，这导致最终用户体验不佳。提高网状网络传输性能的核心挑战是使传输协议能够感知多跳无线网络中存在的复杂干扰。智力优势。这项工作将探索网状网络的传输协议的设计空间。它将集中于两类设计：a）易于实施、公平高效的方案，确保在网络内部检测到拥塞时正确地抑制竞争流量; B）接近最优的方案，估计可用网络容量，并以公平高效的方式将其分配给流量。广泛影响。拟议的工作可以刺激网状网络在未来互联网中的采用，并影响其设计中的架构选择。网状网络已经成为机场、酒店、会议中心、购物中心、教育设施和医院等各种场所的首选网络技术。随着其经济重要性的增加，该项目有望产生影响，寻求提高网状网络的性能。

Contention-Awareness in Mesh Transport: Theory and PracticeMulti-hop wireless mesh networks are becoming increasingly important elements of edge networks in the Internet. These networks of static nodes provide community networking, distributed sensing, and Internet access. In each case, the primary advantage of a mesh is its easy deployability and upgradability.Despite these advantages, mesh networks have not seen widespread adoption. The primary reason for this is a lack of attention to the transport performance of such networks, which leads to poor end-user experience. The central challenge to improving transport performance in mesh networks is to make the transport protocol aware of the complex interference that exists in multi-hop wireless networks. Intellectual Merit. This work will explore the design space of transport protocols for mesh networks. It will focus on two classes of designs: a) easy to implement, fair and efficient schemes that ensure that competing traffic is correctly throttled when congestion is detected inside the network, and b) near-optimal schemes estimate available network capacity and apportion it to flows in a fair and efficient manner.Broad Impact. The proposed work can spur the adoption of mesh networks in a future Internet, and influence architectural choices in its design. Mesh networks are already becoming the networking technology of choice in a variety of locations including airports, hotels, convention centers, shopping malls, education facilities, and hospitals. With their increasing economic importance, this project is poised to make impact, seeking as it does to improve the performance of mesh networks.
