An Efficient Cache Invalidation Strategy in Mobile Information Systems

The development of mobile information systems has brought more advantages for mobile users, enabling them to use mobile devices to get information everywhere and at anytime. However, the application development has limitations due to wireless communications and mobile devices. Caching method needs to overcome some of these difficulties. There are many issues related to caching method, among which is how to guarantee the consistency of the data cached at the clients. In this paper, we propose an efficient strategy for consistent cache at client-side upon data updating at server-side. We carried out experiments on simulation to evaluate the effectiveness of our proposed approach.
