Mobile Ad-hoc Networks (MANET) is an emerging area of research over the past decades. Most current work is centered with different enhancements. This paper discusses to enhance the access of image data in MANETs. Mobile adhoc network consists of mobile nodes that can move freely in an open environment. Communicating nodes in a Mobile Adhoc Network usually interact with other intermediate nodes to establish communication channels. A number of challenges like caching, adopting prefetching technique, open peer-to-peer network architecture, stringent resource constraints, shared wireless medium, dynamic network topology etc are to be addressed in MANET. As MANET is quickly spreading for the property of its capability in forming temporary network without the aid of any established infrastructure or centralized administration, Access rate of image data or Query latency has become a primary concern in MANETs. In this paper focus is on data caching and adopting efficient prefetching techniques to improve or enhance the access rate of data there by reducing the query latency.
