An effective cache-index forwarding over wireless network for the World-Wide Web

Abstract

Caching and prefetching are well-known solutions to the problem of long latency in both wired and wireless networks. Caching is prevalently used to reduce round-trips and network traffic. The prefetching and uploading-prefetching data from fixed hosts on a wired network and uploading to mobile hosts-in the base station for the WWW has been proposed to solve those problems and has shown high performance improvement. The performance of prefetching in the base station can be improved when the base station has the caching information of mobile hosts. Cache-index forwarding can be used to let the base station see information of caching on mobile hosts. Here we propose a method named "CINDEX: Cache-Index Forwarding per Document for the WWW", which sends the information of caching data on mobile hosts per document to the base station to eliminate unessential data prefetching and uploading.
