Recent diversification of mobile computing devices allows a mobile user to own multiple types of devices for different application scenarios, but also results in various restrictions on the performance and usability of these devices. A viable solution to such restriction is to incorporate and interconnect mobile devices towards a personal mobile cloud where these devices can complement each other via cooperative resource sharing, but is challenging due to the heterogeneity of mobile devices in both hardware and software aspects. In this paper, we propose a novel design of resource sharing framework to address these challenges and generically interconnect heterogeneous mobile devices. Our basic idea is to mask the hardware and software heterogeneity in mobile systems by exploiting the existing mobile OS services as the interface of resource sharing, and further develop the resource sharing framework as a middleware in the mobile OS. We have implemented our design over various mobile platforms with diverse characteristics and resource limits, and demonstrated that our design can efficiently support generic resource sharing among heterogeneous mobile devices without incurring significant system overhead or requiring individual system modification.

通过通用设备互连迈向个人移动云

近来移动计算设备的多样化使得移动用户可以针对不同的应用场景拥有多种类型的设备，但也导致这些设备的性能和可用性受到各种限制。这种限制的可行解决方案是将移动设备整合并互连到个人移动云中，这些设备可以通过协作资源共享相互补充，但由于移动设备在硬件和软件方面的异构性而具有挑战性。在本文中，我们提出了一种新颖的资源共享框架设计，以应对这些挑战并通用互连异构移动设备。我们的基本思想是通过利用现有的移动操作系统服务作为资源共享的接口来掩盖移动系统中硬件和软件的异构性，并进一步开发资源共享框架作为移动操作系统中的中间件。我们已经在具有不同特性和资源限制的各种移动平台上实现了我们的设计，并证明了我们的设计可以有效地支持异构移动设备之间的通用资源共享，而不会产生显着的系统开销或需要单独的系统修改。
