The caching paradigm has widely been used in computers, data bases and the Internet to reduce the response time of the applications and to reduce the traffic load in the computer buses or in the networks. These advantages can also be applied in a Mobile Ad Hoc Network (MANET) as the caching paradigm could reduce the interferences due to the traffic overload and it could also increase the availability of the documents due to server disconnections. In this article, we propose a cooperative caching scheme for MANETs. The proposal is supported by the local cache that all the nodes in the MANET possess. In a collaborative way, a node could respond to the demand of other nodes if it is keeping a valid copy of the required document. As a novelty, the demands of the documents are not restricted to specific application messages but they are codified into the messages generated when the path to the …
