CAREER: Interconnected Mobile Computing in Wireless Networks

移动计算已经成为现代生活中不可或缺的一部分。然而，不同的制造限制使得当前的移动设备远不适合随时随地使用。传统的解决方案通过探索各种设计视角之间的权衡，为不同的应用场景设计单独的移动设备，但无法扩展到未来移动应用程序日益增加的复杂性和性能要求。相反，这个项目的愿景是互联移动计算（IMC），它通过无线网络将同一用户拥有的多个移动设备完全互连，并允许这些设备通过协作资源共享相互补充。IMC旨在从根本上消除移动设备之间的物理边界，从而增强提供给用户的移动计算能力。这项研究的成功可以充分释放异构移动设备的潜力，并允许高度普及和认知的移动应用程序插入到人类生活的各个方面。这项研究的结果可能会促进移动计算的新研究方向，并使工业控制、遥感和互联医疗等更广泛的网络物理系统受益。该项目将积极将研究成果应用于本科课程的开发，让代表性不足的学生参与研究，并将研究成果用于K-12教育和推广项目。该项目旨在开发无线网络和移动系统中的关键使能技术，以确保IMC的效率、适应性和通用性。更具体地说，该项目包括三个密切相关的研究重点：(i)通过设计专用于IMC的额外无线通信信道，减少移动设备之间资源共享的无线传输延迟；Ii)通过设计用于资源共享决策的分布式网络算法，确保资源共享对各种网络和系统动态的适应性；iii)通过开发新的移动操作系统接口，系统地支持远程移动系统之间的通用资源访问。提出的技术设计将在软件定义无线电和现成移动设备的中等规模移动测试平台上实施和评估，并将通过大规模基于跟踪的仿真进行验证。

Mobile computing has been an indispensable part of modern life. However, diverse manufacturing limits make current mobile devices far from ideal for being used anytime, anywhere. Traditional solutions design individual mobile devices for different application scenarios by exploring tradeoffs among the various design perspectives, but cannot scale to the increasing complexity and performance requirements of future mobile applications. Instead, the vision of this project is Interconnected Mobile Computing (IMC), which fully interconnects multiple mobile devices owned by the same user via wireless networks and allows these devices to complement each other via cooperative resource sharing. IMC aims to fundamentally remove the physical boundary between mobile devices and hence augment the mobile computing capability provided to the user. The success of this research could fully unleash the potential of heterogeneous mobile devices and allow insertion of highly pervasive and cognitive mobile applications into every aspect of human life. The results from this research are likely to foster new research directions on mobile computing and benefit a broader scope of cyber-physical systems such as industry control, remote sensing and connected healthcare. The project will actively apply the research results into development of undergraduate curriculum, engage under-represented students into research, and exploit the research outcomes for K-12 educational and outreach programs. This project intends to develop key enabling technologies in wireless networks and mobile systems that ensure the efficiency, adaptability and generality of IMC. More specifically, this project consists of three closely intertwined research thrusts: (i) reducing the wireless transmission latency of resource sharing between mobile devices by designing an extra wireless communication channel that dedicates to IMC; ii) ensuring adaptability of resource sharing to various network and system dynamics by designing distributed network algorithms for resource sharing decisions; and iii) systematically supporting generic resource access between remote mobile systems via development of new mobile OS interfaces. The proposed technical designs will be implemented and evaluated over a medium-scale mobile testbed of software-defined radios and off-the-shelf mobile devices, and will also be validated by large-scale trace-based emulation.
