【摘要】 在深入研究缓存失效广播技术的基础上提出了一种基于移动环境的自适应缓存管理机制(ACMS)。该方法根据存取数据的移动客户机的数目,在服务器端动态调整失效报告的内容及广播间隔,在客户端根据时间戳及时间间隔值修改缓存数据。通过对该方法进行性能分析,与现有的缓存机制进行比较,该机制能有效节省能量,提高带宽利用率。更多还原

【Abstract】 A new adaptive cache management scheme(ACMS) in mobile environment is proposed based on the studying of existing cache invalidation broadcasting schemes.The scheme can adjust dynamically the contents of invalidation reports and broadcast interval at the server side according to the number of mobile clients,and change cached data at the client side according to timestamps and broad-cast interval.Through performance analysis of the approach and comparison with existing cache invalidation schemes,it shows that the proposed algorithm can save energy and improve the bandwidth utilization.更多还原
