| ==Example of a Student Project (Demo)==
| |
| ===Content-centric Notification System (CNS)===
| |
| A '''scalable''', '''secure''' and '''timely''' notification system is always a necessary in daily communication. It is especially important in a disaster scenario. E.g., the government will notify the citizens about the status of the recovery, rescue and supply. The victims also need to notify their relatives (and whoever cares about them) their current status. They can also call for help (from ambulance service or any responsible service provided by the government) via such notification systems.

| But the authorization is a big concern in such extreme scenarios. Authorization on a person-by-person basis is obviously not (energy, computation, and networkload) efficient. In such a system, we propose a new authorization system. A person create groups and use his own features (e.g., family name, cellphone number, eye color, etc.) as the challenge question for the group. In another word, he assumes that everyone who wants to join the group should have the knowledge of that information. Via such mechanism, a requester of a group can get authorization from other members of the group or even the network cache, thus save the cost on the group owner.

| Another key feature of the project is the use of the Content-Centric Network (CCN). The new network architecture provides better support for a (topic-based) pub/sub system than the existing IP-based solutions. The demo system leverages the 6 machines in the network-lab running as CCN routers and hooks up with the HTTP translator on the edge of the network.
