Delay Tolerant Network utilizing train for news portal and email services

Delay Tolerant Network (DTN) is an end-to-end network architecture designed to provide communication in highly stressed networking environments. Stressed networking environments are those with intermittent connectivity, large and/or variable delays, and high bit error rate. In this paper, basic concept, system architecture, services scheme, and DTN-based network design for delivering news portal and email services to remote villages by utilizing train as a DTN router and wireless LAN or WiFi as intermediate network will be discussed. To illustrate the system, we perform an experiment by modeling the system based on the network design and then simulate the services.
