Abstract: This paper presents the co-operative based database for ad hoc Mobile Networks (MANET). The main focus of the system is on the nodes that save the queries sent. Queries are used as an index of the data stored in the caches of the nodes. This paper deals about the system formation and detection of demanded data from the cache or from the external database. Different parameters like upper and lower bonds for query caching nodes, average load experience, node bandwidth and hit ratio are analyzed and derived. The proposed method is simulated using NS-2. The proposed system has achieved a better success rate and a lower delay compared to other caching systems.

Keywords: Mobile ad hoc networks, distributed cache, cache indexing, database queries.
