A cache sharing interface for data access in mobile ad hoc networks

Nowadays mobile communication is widespread in the world and has become a necessity in our daily lives. Unlike infrastructured wireless networks, mobile ad hoc networks (MANETs) have no fixed infrastructure such as base stations or access points, and the framework is dynamic owing to frequent changes in both topology and mobile nodes. Most researches, however, focus on the discussion of the shortest path or the highest bandwidth; issues related to the data transmission in MANETs are rarely considered. To deal with the intrinsic properties of MANETs, this paper proposes a cache sharing interface for data access. Under the operation of the proposed mechanism, routes and time span to access data are shortened and the data reusable rate is enhanced to save the use of bandwidth and power consumption of mobile nodes.
