Prefetching Scheme Considering Mobile User's Preference in Mobile Networks

This paper proposes a mobile computing prefetching method considering the user’s interest and the common popularity. For mobile computing environments, there exist restrictions as like bandwidth, latency and traffic. Since, in the present, we prefer the united multimedia mobile information service to the voice-based one, these obstacles are regarded as big problems. To solve those problems, a variety of techniques as well as caching or prefetching have been studied. However most of them are not sufficient in providing the amount of data that the user wants. We suggest a prefetching method to bring information early by using information about the user’s former interest and the popularity. Comparing to the previous methods in numerical results, the proposed method improves the prefetching performance to give the maximum effectiveness and reduces the failure rate of information searching.
