Wireless mesh network performance: throughput and fairness

无线网状网络是一种新的颠覆性技术，为农村和城市用户提供高速的最后一英里接入。例如，多伦多水电公司宣布，他们将建设加拿大最大的WiFi网络，为多伦多居民提供低成本的互联网接入。虽然这种网络的核心构建模块（无线电发射机和基本网络协议）已经存在，但仍存在许多问题。在过去的几年中，我的小组研究了一系列多跳无线网络主题。我们与渥太华的一家小型初创公司合作，建立了加拿大为数不多的无线网格测试平台之一。在提议的研究中，我们将在此基础上解决一个核心挑战：为最终用户提供公平和高带宽（即高吞吐量）的无线网络接入，并通过它连接到互联网。

Wireless mesh networks are a new, disruptive technology to provide high-speed last-mile access to rural and urban users. Toronto Hydro, for example, announced that they will build Canada's largest WiFi mesh to provide low-cost Internet access to Toronto residents. While the core building blocks of such networks (radio transmitters and basic networking protocols) exist, many problems remain. In the past few years, my group has worked on a range of multi-hop wireless network topics. In conjunction with a small Ottawa startup company, we built one of the few wireless mesh testbeds in Canada. In the proposed research, we will build on this basis to address one of the core challenges: providing end-users with fair and high-bandwidth (i.e., high throughput) access to the wireless mesh and through it to the Internet.
