A number of DTN-based projects for graduate students are currently available. These projects are mainly for graduate students, however, undergraduate students are highly encouraged to participate. A very interesting and practical project for undergraduate students in this area is design of a DTN network using a Lego Mindstorms Nxt. Here is a tutorial paper about delay tolerant network. We are currently working on a number of issues in DTN:
1- Anycast routing and how to interface disconnected DTN regions to the Internet.
2- Security in DTN; each intermediate node can have the custody of its messages. New security measurements must be considered to ensure the intermediate nodes cannot access or modify messages they have custody of.
3- Implementing Car-to-Car Communication or a Vehicular-Delay-Tolerant Network.
4- Implementing a TCP/IP -based DTN protocols using a Linux based system.
5- Describing the Inter-domain protocols between a VDTN and a non-VDTN (e.g., Internet) or multiple VDTNs administered by different organizations.
6- Using the ONE simulator to implement a VDTN system with different routing protocols.
5- Using omni-directional wireless optical communication systems in Vehicular DTN, possibilities, and challenges.
6- Applications of Mobile-DTN: Tracking hikers, animals, etc. using Google map
7- Predictions of future connectivity information - the important issue here is how to choose an appropriate next hop in Vehicular-DTN.
