SHF:CSR:Small: Perpetuum Mobile: Orchestrating the Provisioning of Pervasive Resources for Emerging Mobile Applications

该项目开发Perpetuum Mobile，这是一个统一的框架，使移动开发人员不必使用不同的低级编程接口来访问有效执行新兴移动应用程序所需的外部资源。移动设备不断增长的计算能力正在被移动应用程序更快增长的资源需求所超越。通过使用由云服务器、台式计算机或其他移动设备提供的分布式资源，可以有效地满足这些需求。然而，现有的访问外部资源的方法无法提供一个统一和统一的途径来将异质和无处不在的资源与新兴的移动应用程序集成在一起。移动开发人员别无选择，只能通过软件抽象使用不同的编程接口和协议，无法有效满足移动用户和开发人员以及设备所有者和管理员的需求。为了解决这个问题，Perpetuum Mobile选择最符合要求的设备，按需在任何选定的联网设备上部署外部资源，并提供对资源的统一访问。该项目的最终技术目标是使移动应用程序能够像目前访问标准Web服务一样，直接、高效、可靠和安全地访问任何联网设备托管的资源。为了满足移动应用程序的执行需求，Perpetuum Mobile发展了微服务模式：它仔细管理微服务，并通过使用结合了移动应用程序市场和服务存储库功能的新软件基础设施组件在运行时部署它们。通过应用用于表达需求的格模型和基于加权距离的选择启发式算法，进一步有效地识别最合适的服务提供设备。最后，本项目确定并寻求安全和隐私问题的解决方案，这些问题威胁到所开发的执行模型的安全性。通过提供看似无限的资源，在该项目的支持下创建的技术将为下一代移动、物联网和可穿戴应用程序奠定基础。该项目将招募不同的参与者，同时将创建的技术公开供采用、培训和实验。

This project develops Perpetuum Mobile, a unified framework that unburdens mobile developers from using dissimilar, low-level programming interfaces to access external resources required for the efficient execution of emerging mobile applications. The ever increasing computational power of mobile devices is being surpassed by the even faster growing resource demands of mobile applications. These demands can be effectively fulfilled by using distributed resources, provided by cloud servers, desktop computers, or other mobile devices. However, existing approaches for accessing the external resources fail to provide a unified and uniform avenue for integrating heterogeneous and pervasive resources with emerging mobile applications. Mobile developers have no choice but to use dissimilar programming interfaces and protocols through software abstractions that cannot effectively meet the requirements of mobile users and developers as well as device owners and administrators. To address this problem, Perpetuum Mobile selects devices that best satisfy the requirements, deploys the external resources on any selected network-connected device on-demand, and provides a uniform access to the resources.The ultimate technical objective of this project is to make it as straightforward, efficient, reliable, and secure for mobile applications to access the resources hosted by any network-connected device as it is currently to access standard web services. To meet the execution requirements of mobile applications, Perpetuum Mobile evolves the microservices pattern: it carefully curates microservices and deploys them at runtime by using a new software infrastructure component that combines features of mobile application markets and service repositories. It further identifies the most suitable service-providing device efficiently by applying a lattice model for expressing requirements, and a weighted distance based selection heuristic. Finally, this project identifies and seeks solutions for the security and privacy problems that threaten the safety of the developed execution model. By providing seemingly unlimited resources, the technologies created under the auspices of this project will form the foundation for the next generation of mobile, IoT, and wearable applications. The project will recruit a diverse group of participants, while making the created technologies publicly available for adoption, training, and experimentation.
