Mobile Ad-hoc NETwork (MANET) is a collection of mobile nodes forming an ad hoc network without the assistance of any centralized structures. There are many protocols to improve data accessibility and reduce query delay in MANETs. Some of these protocols have adopted the cooperative caching scheme, allowing multiple mobile hosts within a neighborhood to cache and share data items in their local caches. Cross-layer optimization has not been fully exploited to further improve the performance of cooperative caching. A cluster based cooperative caching scheme is proposed and a cross-layer design approach is employed to further improve the performance of cooperative caching and prefetching schemes.
