项目摘要
Whether on the go, at home, or at work, people increasingly rely on connecting to the Internet via 802.11 (WiFi) networks. It is anticipated that over 20 billion WiFi chipsets will be shipped between 2016 and 2021 and the number of public WiFi hot spots in the world is projected to increase from 94 million in 2016 to 542 million by 2021. Despite the introduction of high speed 4G and 5G cellular technologies, WiFi remains the dominant technology for wireless communications on mobile devices. In 2016, 60% of cellular network traffic was offloaded to WiFi networks and this number is projected to continue to increase. Recent work has found that home WiFi networks are more often the bottleneck in delivering data than the ISP link. Another recent study reports that on average there are 7 devices in every home and the median number of access points seen from a home network in developed countries is 20. Obtaining peak throughput in such environments is extremely challenging because radio spectrums are shared by WiFi devices (e.g., access points, computers, smart phones, tablets, TVs, and game consoles) and non-WiFi devices (e.g., wireless keyboards and mice and microwave ovens). Furthermore, the increasing popularity of WiFi devices exacerbates the problem. It is therefore imperative that we understand how to optimize performance in situations that include dense deployments of WiFi devices. The focus of our research is to develop tools and techniques to improve the throughput of WiFi networks, especially in environments where performance is impacted by mobility, WiFi or non-WiFi interference, and in dense deployment scenarios. The overarching goal is to improve the user experience by increasing the throughput of their devices when using 802.11 (WiFi) networks. Potential benefits to Canada would be an increase in the number of highly qualified, high salaried, tax paying, employees at Google and other companies in Canada. Improved WiFi communication should reduce delays and increase revenues for Canadian companies that sell products via the Internet (studies show that delays decrease revenues).
无论是在旅途中、在家还是在工作中,人们越来越依赖于通过802.11(WiFi)网络连接到互联网。 预计2016年至2021年期间将有超过200亿个WiFi芯片组出货,全球公共WiFi热点的数量预计将从2016年的9400万个增加到2021年的5.42亿个。尽管引入了高速4G和5G蜂窝技术,但WiFi仍然是移动的设备上的无线通信的主导技术。 2016年,60%的蜂窝网络流量被卸载到WiFi网络,预计这一数字将继续增加。 最近的研究发现,家庭WiFi网络往往是传输数据的瓶颈,而不是ISP链路。 最近的另一项研究报告称,平均每个家庭有7台设备,发达国家家庭网络中接入点的中位数为20个。 在这样的环境中获得峰值吞吐量是极其具有挑战性的,因为无线电频谱由WiFi设备共享(例如,接入点、计算机、智能电话、平板电脑、TV和游戏控制台)和非WiFi设备(例如,无线键盘和鼠标以及微波炉)。 此外,WiFi设备的日益普及加剧了该问题。 因此,我们必须了解如何在密集部署WiFi设备的情况下优化性能。 我们研究的重点是开发工具和技术来提高WiFi网络的吞吐量,特别是在性能受到移动性,WiFi或非WiFi干扰影响的环境中,以及密集部署场景中。 首要目标是通过增加使用802.11(WiFi)网络时设备的吞吐量来改善用户体验。对加拿大的潜在好处将是增加谷歌和加拿大其他公司的高素质、高薪、纳税员工的数量。改善WiFi通信应减少延迟,并增加通过互联网销售产品的加拿大公司的收入(研究表明,延迟减少收入)。
