Cooperative data caching with prefetching in mobile ad-hoc networks

摘要

This paper investigates different caching strategies proposed in the recent past and tries to highlight the merits of proposed methods. The major issues on which emphasis is given in this paper is co-operative caching which allows the sharing and coordination of cached data among multiple nodes, can further explore the potential of the caching techniques. Due to mobility and resource constraints of ad-hoc networks, cooperative caching techniques designed for wired networks may not be applicable for ad-hoc networks. In this paper we have proposed hybrid of prefetching and cache the data approach. Another area which we have addressed in this paper is placement of replica in the network because geographically replicating popular objects in the network speeds up the availability of data and at the same time the cost would also reduce for keeping the up-to-date data.
