基于HTML5技术的Widget引擎内容缓存模型及实现

HTML5-based content cache algorithm design and implementation on mobile Widget engine

针对移动Widget无法脱机访问或网络延迟现象严重问题,提出了一种基于HTML 5.0技术的移动Wid-get引擎内容缓存模型,将网络端数据进行智能的下载和存储,通过使用HTML 5.0技术,合理地安排各种移动Widget应用的网络数据;同时根据用户的访问信息和移动Widget技术的原理特性,使用缓存淘汰策略、充分利用缓存空间使系统具有较好的性能。最后通过实验验证该模型可以有效解决Widget脱机访问和网络不良问题,从而提高访问速度和减少数据流量、节省终端电量和资源的消耗。

This paper presented the HTML5-based content cache algorithm design and implementation of Widget engine on mobile intelligent terminal. This algorithm intelligently downloaded and stored the network data using HTML 5, and properly arranged various mobile Widgets network datum by applying the technology on the internal storage and cache. According to the customers＇ visiting information,and using the theory of the technology of the mobile＇Widget, designed a simple and feasible caching refreshing algorithm to make the best use of cache space to achieve the better perforrr/anee of the system. The feasibility of the proposed algorithm is verified and its advantages are testified by the experiment.
