A collaborative cache approach for mobile ad hoc networks

The main contribution of this article is to propose a collaborative and distributed cache mechanism tailored for ad hoc networks. Each node´s cache is partitioned into a shared area and a private area. The proposed collaborative cache is formed by each node´s shared area, which is used to store contents relevant to the group, while the private area is used to store information relevant to its owner. Empirical results have shown that our collaborative cache mechanism can significantly reduce the amount of network traffic, latency and energy consumption as well as the server´s load.
