Novel Approaches for Integrating Web Caching and Mart1 Clustering Based Pre-fetching Technique

5.1 INTRODUCTION As discussed in previous chapter (chapter 4), Web caching and Web pre-fetching are two well known techniques used for enhancing the performance of Web-based information retrieval system. One of the ultimate research objectives of this thesis research work mentioned in chapter 1 is to identify and experiment Web caching replacement algorithms and to integrate Web caching and clustering-based Web pre-fetching using MART1 so as to optimize the Webpage retrieval speed and thus to reduce the latency in accessing a Webpage. Section 5.2 introduces the need and significance of Web caching and clustering-based Web pre-fetching. Section 5.3 elaborates the research progress in Web caching and pre-fetching. Section 5.4 describes the various Web caching policies and its comparative performances features. Section 5.5 portrays the proposed MLFU algorithm and section 5.6 portrays the proposed MPLFU algorithm. Section 5.7 illustrates and explains the results of experiments and the discussions based on the results obtained under various experiments.
