DEMO-OPPNET is a demonstrator running on Linux that allows a non-specialist user to create an opportunictic network and test some simple opportunistic applications.
An opportunistic network is a network in which mobile devices communicate thanks to direct short-range transmissions, without any fixed infrastructure (thus with no access to the Internet). Each device can store messages, so that information can propagate in the whole network as mobile devices come into contact with each other.
DEMO-OPPNET uses Wi-Fi (in ad hoc mode) for device-to-device transmissions. So it can be installed on any PC running Linux that is equipped with a Wi-Fi interface. Moreover, it is possible to externalize the user application on a smartphone or a tablet, provided that a Bluetooth interface is available.
The proposed applications are webapps (running in a web browser) :
In addition, DEMO-OPPNET allows the user to connect a usual mailer in order to take benefit from an opportunistic mailing system.
DEMO-OPPNET relies on the DoDWAN middleware plateform to ensure the communication in the opportunistic network. DoDWAN provides a network API (for publish/subscribe applications as well as CRDT-based applications) that is used by the applications proposed in the demo.
