Agenda Test environment setup Challenges Achievements Works to be done

Test environment setup

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

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

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