Replacement strategy for semantic caching based on incremental clustering
基于增量聚类的语义缓存替换策略*

To improve system performance and overcome narrow bandwidth and disconnection of mobile computing environment,it is very important to use the semantic caching to manage location dependent data.This paper gave the formal definitions of semantic caching.Then analyzed the FAR(furthest away replacement) replacement strategy,developed a new replacement strategy named data clustering FAR(DC-FAR),which based on the previous query data.At last,compared the FAR and DC-FAR replacement strategy through the experiment.The experiment shows that the DC-FAR was more effective than FAR in the theory and experimentation.
