摘要
由于无线环境中的网络和手持设备的限制,缓存机制在提高移动系统性能方面发挥着重要作用。本文描述了适用于无线LAN的Web缓存系统EasyCache系统的实现,给出了基于数据挖掘理论的移动主机端缓存数据预取算法SEDP。模拟实验数据表明SEDP算法取得了良好的效果。
Caching mechanism play an important role in improving the performance of mobile systems which must face the constraints in handheld devices and mobile network. This paper describes the implementation of EasyCache system, a Web caching system for wireless I.AN, and presents the data prefetching algorithm SEDP for mobile host＇s cache which refers to data mining theory. Results from simulation experiments show the SEDP in EasyCache system gets better effects.
