Current cellular technologies fail to provide services with data rates that are anywhere close to the speeds available over typical Wireless LANs (WLANs). Large-scale deployments of WLANs have the potential to provide ubiquitous high data rate coverage, but the cost of deployment and management of a large number of WLAN access-points for providing full coverage is prohibitive. On the other hand, scattered deployments of WLAN hotspots are useful but they fail to provide any level of service assurance to mobile users.This project aims at developing the foundations for a system that will provide assured data services over a wide-area to data-intensive applications for mobile users using an economically scalable infrastructure consisting of heterogeneous technologies, and to demonstrate it with a prototype implementation. The project involves the following research objectives: 1) to develop solutions for hotspot deployment that enable the best possible services for mobile users through a limited number of hotspots; and, 2) to design solutions for meeting the needs of delay tolerant applications using dynamic resource control.The proposed research is transformative as it will build the foundations for bringing high-speed data services to mobile users through scattered hotspots and it has the potential to open up new research avenues along the lines of assured but interruptible services. A number of applications covering the entertainment, industrial and commercial sectors will get impacted by this research. Special efforts will be made to recruit women and minority students for this project.

目前的蜂窝技术无法提供任何接近典型无线局域网（wlan）可用速度的数据速率服务。大规模部署WLAN具有提供无处不在的高数据速率覆盖的潜力，但是为提供全覆盖而部署和管理大量WLAN接入点的成本令人望而却步。另一方面，WLAN热点的分散部署是有用的，但它们不能为移动用户提供任何级别的服务保证。该项目旨在开发一个系统的基础，该系统将使用由异构技术组成的经济可扩展基础设施，为移动用户提供广域数据密集型应用程序的可靠数据服务，并通过原型实现进行演示。本项目的研究目标如下：1)开发热点部署解决方案，通过有限的热点为移动用户提供最佳服务；2)利用动态资源控制设计满足容延迟应用需求的解决方案。拟议的研究具有变革性，因为它将为通过分散的热点向移动用户提供高速数据服务奠定基础，并有可能沿着可靠但可中断的服务开辟新的研究途径。涵盖娱乐、工业和商业领域的许多应用将受到这项研究的影响。将特别努力为这个项目招收妇女和少数民族学生。
