Cache Coherency Analysis Based on Peer Mobile Client

In mobile computing environment,one of the important factors to ensure cache validity is maintaining cache coherency.In this paper,we analyzed the traditional cache coherency scheme,and described a cache scheme based on peer mobile client,which applied the new concept on the time stamp scheme based on windows.This made every mobile client to be a temporary virtual server to send out caching information.The simulated experiment showed that the proposed technique was effective in improving the mobile cache hit ratio and maintained cache coherency to a certain extent.
