EAGER: Supporting Social Applications in a Hybrid Architecture with CR-Enabled Devices

本项目的目标是通过利用认知无线电网络(CRN)和移动自组织网络(MANET)相结合所带来的好处，研究在提高社交应用性能方面起关键作用的一些具有挑战性的问题。这项研究的动机是观察到：(I)CRN和MANET缺乏成功和实际的应用，尽管近年来两者都得到了广泛的研究；以及(Ii)整合CRN和MANET以推出新的移动社交应用和提高现有移动社交应用的性能的好处。在该项目中，使用图论方法来实现可扩展的高清视频聊天，以提高限时信息传播的性能，并增强启用CR的设备之间的信息共享的私密性。此外，利用网络形成博弈来构建社交应用感知的网络拓扑，以提高容量和性能；并采用统计方法来研究拓扑控制对社会行为和反之的影响。该项目的预期结果包括新的方法和理论，以提高现有的移动社交应用程序的性能，并支持新的移动社交应用程序。该项目的成功将对可预见的CRN和MANET混合环境中的社会应用的理论和实践方面产生重大影响。研究结果将通过高质量的出版物以及在有重点的讲习班和会议上的介绍加以传播。项目成果将为业界提供指导，并可能被业界采纳，以提高服务的可用性和完整性。

The objective of this project is to investigate a number of challenging problems that play critical roles in enhancing the performance of social applications by taking advantage of the benefits brought by integrating cognitive radio networking (CRN) and mobile ad hoc networks (MANET). This research is motivated by the observations of (i) the lack of successful and practical applications of CRN and MANETs, though both have been extensively studied in recent years; and (ii) the benefits of integrating CRN and MANET to launch new and to enhance the performance of existing mobile social applications. In this project, graph theoretical approaches are employed to enable scalable HD video chat, to improve the performance of time-bounded information dissemination, and to enhance the privacy of information sharing among the CR-enabled devices. Moreover, network formation games are exploited to construct social-application-aware network topologies for capacity and performance enhancement; and statistical approaches are adopted to investigate the impact of topology control on social behaviors and vice version. The expected results of this project include novel methodologies and theories to enhance the performance of existing and to enable new mobile social applications. The success of this project will have strong impact on both the theoretical and the practical aspects of social applications in the foreseen hybrid environment of CRN and MANETs. The research findings will be disseminated through high-quality publications as well as presentations in focused workshops and conferences. The project outcomes will provide guidance to and may be adopted by industry for enhancing service availability and integrity.
