A Transparent Cache-Based Mechanism for Mobile Ad Hoc Networks

Mobile ad hoc networks (MANETs) enable all mobile nodes to communicate each other without base stations or access points, and the transfer of data packets is completed through the relay among all mobile nodes. However, a MANET is a self-organizing and adaptive wireless network formed by the dynamic gathering of mobile nodes, and the topology of a MANET frequently changes. To cope with the intrinsic properties of MANETs, a transparent cache-based mechanism is proposed in this paper. With the aid of the mechanism, the repetition of data and data path occurring in a MANET could be cached in some special mobile nodes. Routes and time span to access data are therefore shortened, and the data reusable rate is enhanced to reduce the use of bandwidth and the power consumption of battery
