Cross-layer design for cooperative caching in mobile ad hoc networks

In this paper we employ a cross-layer design approach to improve the performance of combined cooperative caching and prefetching schemes. The cross-layer information is maintained in a separate data structure and is shared among layers. We also combine prefetching with cooperative caching to further improve performance. We carried out extensive simulation experiments and compared various approaches including simple caching, cooperative caching with prefetching, and cooperative caching without prefetching. The experimental results that demonstrate the performance of the proposed approach are presented.
