MobileFBP - 針對安卓應用程式之動態轉移系統

Abstract

自從智慧型手機日漸普及以來，手機的處理效能與電池續航力一直是開發者所急欲突破之瓶頸；然而礙於體積的限制，手機上暫時無法裝配高效能的處理器與高容量的電池，因而無法處理重量級的工作與高複雜度的應用程式。若可將這些工作轉移至雲端伺服器作處理，將有機會改善上述窘境。在這篇論文中，我們將提出一套虛擬雲端手機服務系統及其對應之手機應用程式界面(API)。使得手機程式開發者只要遵循Flow-Based Programming Model並套用其API，即可將手機程式搬移至雲端系統，使得手機上的程式可以借助雲端虛擬手機的運算能力，以提高處理效能並降低電量消耗。

Fundamentally, the computing resources on a mobile device are limited by the form factors of the device. For a mobile application to overcome this resource limitation, it might seek and utilize extra resources in the cloud. Client-server model is a traditional method to utilize the cloud resources, but it requires the programmer to partition applications and establish the server environment, which are not simple tasks. Thus, we investigate procedure offloading techniques which migrate the program process to cloud system dynamically without requiring the programmer to provide a cloud service in advance. In this thesis, we proposed a unified application development framework, called MobileFBP, which leverages the Flow-Based Programming (FBP) paradigm to enable the development of portable mobile applications to run accross different mobile-cloud computing environments with scalable performance. The framework further supports heterogeneous cloud systems to reduce the execution time and power consumption with multicore processors, GPU, and hardware accelerators. We discuss the design of the MobileFBP framework and present several usage scenarios in our experimental studies.
