Part I: Introduction to the main concepts of Delay- and Disruption-Tolerant Networking
Part II: Service Target driven routing and forwarding for DTNs
Part III: UPNs and DTNs as complementary technologies for ubiquitous connectivity

In this tutorial, we will investigate the incentives needed in order to convince the end-, home-user to shift into the UPN paradigm and share his broadbandInternet connection. In particular, we will show that the end-user can gain unlimited connectivity, when mobile but without any impact whatsoever on the performance of his own connection: if the micro-provider shares his unused bandwidth with guest-users then: (i) sharing has no impact to the home-user's connectivity speed and (ii) the guest-user can have connectivity when mobile. We will then conclude highlighting the most important issues that still remain open and we will give directions for future research. According to the above, this tutorial is going to last for three hours and is going to be split in the following three main parts: (i) Introduction to the main concepts of Delay- and Disruption-Tolerant Networking, (ii) Service Target driven routing and forwarding for DTNs and (iii) UPNs and DTNs as complementary technologies for ubiquitous connectivity.
