The proposed research is directed towards developing networking solutions for ubiquitous computing - which has the promise to open up many new applications leading to an overall improvement of productivity at our homes and offices and would result in a better quality of life. The networking challenge is to design seamless, high quality wireless adhoc communication among a large number of small inexpensive computers. These nodes are expected to self-organize into networks capable of discharging complex computing and communication functionalities which lead to acute resource limitations. The constrained resources are bandwidth, power and buffer memory. Furthermore, the dynamic nature of the topology and the geographical separation of nodes require distributed control. The proposed research seeks to provide the desired quality of service to users in spite of the resource limitations. We note that bandwidth, memory and power are interdependent resources. The coupling is due to the fact that the temporary scarcity of one can be compensated by leveraging the availability of another. This interdependence can be exploited to design a comprehensive management scheme, for power, memory and bandwidth, which significantly enhances the traffic carrying capability of wireless networks. The next key observation is that in ubiquitous computing individual nodes are idle most of the time, but must handle occasional bursts of activity. The traffic handling capability increases many-fold if idle resources of the neighbors are leveraged. The research goal is to design an optimal distributed control framework which uses local observations and partial information of the resource requirements and availabilities at other nodes to attain (a) an efficient and comprehensive utilization of individual resources and (b) a judicious usage of others idle resources when the individuals resources are not sufficient. The resulting protocols are expected to be robust to variations in networking traffic and dynamic topological changes on account of mobility.The activity will promote the training of high caliber students to fill the expanding need for capable scientists and engineers in the information technology field. Undergraduates will be involved in wireless research through creative design projects. The design projects will target adhoc applications of societal significance such as adhoc networking of vehicles e.g., cars for preventing low-visibility related accidents. Supervision of doctoral research will be a core component of the overall activity.The overall education mission of the home institution (University of Pennsylvania) will be furthered through the design of two new courses in the wireless area at undergraduate and graduate level, and introduction of seminars and industry collaborations. The outreach activity will motivate women towards careers in engineering. The specific plan is to reach out to women students by participating in (a) girl scout activities as group leader/mentor and (b) local IEEE student branches, society of women in engineering (SWIE) and synergistic activities in local community colleges, involve them in innovative projects and subsequently proactively hire women PhD students.

这项拟议的研究旨在为无处不在的计算开发网络解决方案-这有望打开许多新的应用程序，从而全面提高我们家庭和办公室的生产力，并带来更好的生活质量。网络面临的挑战是在大量小型廉价计算机之间设计无缝、高质量的无线自组织通信。这些节点被期望自组织成能够执行复杂的计算和通信功能的网络，这导致了严重的资源限制。受限的资源是带宽、功率和缓冲存储器。此外，拓扑的动态特性和节点在地理上的分离需要分布式控制。拟议的研究试图在资源有限的情况下向用户提供所需的服务质量。我们注意到，带宽、内存和功率是相互依赖的资源。这种耦合是由于这样一个事实，即一个的临时稀缺性可以通过利用另一个的可用性来补偿。可以利用这种相互依赖关系来设计一种针对功率、内存和带宽的综合管理方案，从而显著增强无线网络的流量承载能力。下一个关键的观察是，在普适计算中，各个节点大部分时间都是空闲的，但必须处理偶尔爆发的活动。如果利用邻居的空闲资源，流量处理能力将增加许多倍。研究目标是设计一种最优分布式控制框架，该框架利用局部观测和其他节点的资源需求和可用性的部分信息来获得(A)个体资源的高效和综合利用以及(B)当个体资源不足时对其他闲置资源的合理使用。预计所达成的协议对网络流量的变化和因移动而引起的动态拓扑变化具有很强的适应能力，活动将促进培养高素质的学生，以满足对信息技术领域对有能力的科学家和工程师的日益增长的需求。本科生将通过创意设计项目参与无线研究。设计项目将针对具有社会意义的特别应用，例如车辆的特别联网，例如防止低能见度相关事故的汽车。对博士研究的监督将是整个活动的核心组成部分。总部机构(宾夕法尼亚大学)的总体教育使命将通过在本科生和研究生水平设计两门新的无线领域课程，以及引入研讨会和行业合作来进一步推进。这项外展活动将激励妇女投身工程行业。具体计划是通过以下方式接触女学生：(A)作为小组组长/导师的女童子军活动；(B)IEEE当地学生分会、工程学妇女协会(SWIE)和当地社区大学的协同活动，让她们参与创新项目，然后积极聘用女博士生。
