7. Overall architecture

8. Delay-Tolerant networking BP Application LayerBundle Protocol Convergence LayerLink layer (TCP/IP) RFC 5050 Interoperability DTN 2

9. Layered architecture

10. Network Setup and Email System Integration ABDULLAH AZFAR NordSecMob

11. Agenda Test environment setup Challenges Achievements Works to be done

12. Test environment setup

13. Challenges Finding exact configuration for installing DTN2 ◦ Use Ubuntu 8.04 (Hardy Heron) LTS ◦ Finding dependency packages ◦ Finding the correct database Configuring the AIROS Bullet devices Installation of DTN2 Configuring dtn.conf file

14. Achievements Network setup completed DTN2 running on three machines Bundles can traverse among three machines DTN2 machines can assign automatic IP to the Android machine through DHCP server

15. Works to be done Installation of POSTFIX as email system Integrating POSTFIX with DTN2 Integration testing with Android Testing active download/upload time
