CAREER: Realizing the Potential of Wireless Adhoc Networks Through Holistic Resource Allocation

该研究旨在开发 网络解决方案的无处不在的计算-这有希望开辟许多新的应用程序，导致全面提高生产力在我们的家庭和办公室，并会导致更好的生活质量。网络的挑战是设计无缝的，高质量的无线adhoc通信之间的大量小型廉价的计算机。预计这些节点将自组织成网络，能够释放复杂的计算和通信功能，导致严重的资源限制。 受约束的资源是带宽、功率和缓冲存储器。 此外，拓扑的动态特性和节点的地理分离需要分布式控制。拟议的研究旨在提供所需的服务质量给用户，尽管资源的限制。我们注意到，带宽、内存和电源是相互依赖的资源。 这种耦合是由于这样一个事实，即一个暂时的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性来设计针对功率、存储器和带宽的综合管理方案，这显著增强了无线网络的业务承载能力。 下一个关键的观察是，在普适计算中，单个节点在大部分时间都是空闲的，但必须处理偶尔的突发活动。 如果利用邻居的空闲资源，则业务处理能力增加许多倍。研究目标是设计一个最优的分布式控制框架，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，以实现（a）有效和综合利用单个资源和（B）当单个资源不足时，明智地使用其他空闲资源。该活动将促进高素质学生的培养，以满足信息技术领域对有能力的科学家和工程师日益增长的需求。 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殊应用，例如车辆的特殊网络，汽车，以防止低能见度相关的事故。 对博士研究的监督将是整个活动的核心组成部分。通过设计本科生和研究生阶段无线领域的两门新课程，以及引入研讨会和行业合作，将进一步推进家乡机构（宾夕法尼亚大学）的整体教育使命。 外联活动将激励妇女从事工程职业。 具体计划是通过以下方式与女学生接触：（a）作为小组领导/导师参加女童子军活动;（B）参加工程师协会地方学生分会、工程界妇女协会和地方社区学院的协同活动，让她们参与创新项目，随后积极聘用女博士生。

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.
