Improving K-copy intelligent caching efficiency based on multi-channel protocol in DTNs- A Survey

Abstract

Mobile nodes in some challenging network scenarios suffer from intermittent connectivity and frequent partitions e.g. battlefield and disaster recovery scenarios. Disruption Tolerant Network (DTN) technologies are designed to enable nodes in such environments to communicate with one another. In this paper, our main focus is on improvement of caching efficiency. So, in this paper we use K- copy intelligent scheme for caching scheme. However in previous paper, author already use this caching scheme but he use in single channel. And we use this scheme for multiple channels. Along with Ad hoc on demand distance Vector (AODV) for message routing protocol. We conduct extensive simulation studies to evaluate efficiency of K-copy intelligent scheme for multi-channel over single channel.
