Design and Implementation of Platform-Independent Offloading System for a Mobile Web Environment

Abstract

Increasingly, smart phones are becoming one of the most popular mobile devices in personal computing environment. As the need for a variety of mobile applications is increasing, the target mobile platform is a primary concern for mobile application developers. To reduce design complexity for different platforms and enhance the compatibility of applications on various mobile OSes, a JavaScript-based web environment became a main target framework for smart phone applications. Computing-intensive and rich graphics-based applications in a smart phone may fully utilize the CPU, and consume a large amount of the battery power accordingly. In this paper, we propose a platform-independent offloading system, which is a delegated system for a mobile web environment. Our offloading architecture is implemented in a built-in proxy system where the original web resources are selectively divides into a lightweight client code and a computationally heavy code running on the server system. Our evaluation shows that our mobile offloading system increases the response time of the application running in the web browser, and enables a high workload application to run on relatively low-end mobile devices. In addition, this method reduces power consumption of the device. Therefore, our web-based offloading architecture creates a new mobile computing environment, and can be applied various OS platforms of mobile devices.
