Some recent studies have shown that cooperative caching can improve system performance on wireless P2P networks, such as ad hoc networks and mesh networks. However, all these studies are at a very high level, leaving many problems of design and execution unanswered. This solution not only reduces data copy overhead between kernel space and kernel space, but also allows data pipes to reduce end-to-end delay. We also studied the effects of different MAC layers, such as ad hoc networks based on 802.11 and multi-interface-multichannel networks, on cooperative cache performance. Our results show that the asymmetric approach overcomes the symmetric approach in traditional ad hoc networks based on 802.11 eliminating most of the processing overhead. In mesh networks, the asymmetric approach can significantly reduce the access delay to the data compared to the symmetric approach due to the data pipelines.
