Mobile Ad Hoc NETworks (MANETs) are dynamic in nature, Links between nodes may constantly change as nodes move around, enter or leave the network, and therefore, a reliable caching scheme is more difficult to achieve. This paper proposes a server based architecture to provide efficient and reliable caching in MANET environments which also minimizes the delays in answering node queries. Nodes can take on one of two possible roles: Caching Nodes (CNs) and Query Directories (QDs). A QD's task is to cache queries submitted by the requesting mobile nodes, while the CN's task is to cache data items (responses to queries).
