Research on Mobile Web Cache Prefetching Technology Based on User Interest Degree

Abstract

In wireless environment, cache and prefetching technology play a very important role in improving the performance of web access. The features of mobile users and wireless networks prefetching mechanism is studied in this paper and proposed a prefetching algorithm based on the mobile user interest degree. In this algorithm, calculate the size of interest degree for mobile users based on web log data to get prefetching pages, compare the size of the cache hit rate by combining prefetching pages and LRU algorithm. By simulation, it finds that the algorithm can effectively improve the cache hit rate.
