Executive Summary

In this paper, the authors propose a cache consistency maintenance scheme called Thread Based Cache Consistency Model (TBCCM), for mobile environment. It lies on the following four key features. Use of log at both server and mobile user's cache maintains data consistency. Use of Thread Agent (TA) at both client & server, use of log database at server, use of Migration Thread Agent at serve. Since log is maintained in both server and client it is easy for server as well as client to make their data object reliable. The data object is reliable due to the usage of log comparison technique. Thread Agents at server and client make an internal request response operation(s) to access or update data object.
