Executive Summary

The security and cache consistent scheme presented in this paper mitigates security attacks in query nodes of server control cache mode in mobile networks. It eliminates fake requests in query nodes. It works on a cache consistency scheme based on a previously proposed architecture for caching database data in MANETs. The consistency scheme is server-based in which control mechanisms are implemented to adapt the process of caching a data item and updating it by the server to its popularity and its data update rate at the server. The security mechanism implements methods to handle disconnections of Query Directory (QD) and Cache Node (CN) nodes from the network and to control how the cache of each node is updated or discarded when it returns to the network
