Intentional Caching in Disruption Tolerant Network
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2016, Vol 3, Issue 1
Abstract
Disruption Tolerant Network (DTN) is a networking architecture that is designed to provide communications in the most unstable and stressed environments. DTN route network messages through intermittently connected mobile devices. It uses carry-and-forward method for data transmission. The greatest challenge in DTN network is to reduce the data access delay between the sender and receiver. The solution is to intentionally cache data into a set of Network Caching Nodes (NCNs), which have high accessibility and buffer capacity. Its specify an efficient scheme for selecting NCNs and its associative caching nodes. Latest data items are cached on the NCNs and cache replacement is based on the popularity of data. Through the simulation verify the performance of the system.
