A dynamic caching mechanism for mobile ad hoc networks

Nowadays people could travel around for work and conferences by using wired or wireless communication to receive information and data immediately. A mobile ad hoc network (MANET) is a self-organizing and dynamically reconfigurable wireless network without base stations or access points. Due to the high mobility of mobile nodes (MNs), the topology of a MANET frequently changes. A dynamic caching mechanism is proposed in this paper to cope with the intrinsic properties of MANETs. With the aid of the proposed mechanism, the repetition of data and data path occurring in a MANET could be cached. The data reusable rate is enhanced to reduce the bandwidth and the power consumption of MNs; routes and time span to access data are also shortened.
