DoDWAN Apps for Android smartphones
DoDWAN Apps is a communication application suite that has been developed by members of the CASA research team in the IRISA computer science laboratory, at Université de Bretagne-Sud (France). It is based on the DoDWAN middleware platform.
With DoDWAN Apps a user can locate other users nearby, and exchange different kinds of documents with these users (text and voice messages, pictures, PDF files, etc.).
Devices running DoDWAN communicate together in a so-called “opportunistic ad hoc” mode, using direct short-range radio transmissions (DoDWAN makes uses of the Wi-Fi ad hoc mode). In order to use DoDWAN no connection to a Wi-Fi access point or to a 3G network is thus required. All devices running DoDWAN collaborate so as to forward messages: a message can hop from device to device, and reach a destination that is far beyond the direct radio range of the sender.
Features (version 2.4.0)
DoDWAN Apps is available for Android smartphones. To date, DoDWAN Apps is compatible only with Android 2.2 and Android 2.3.
Version 2.4.0 of DoDWAN Apps requires a rooted smartphone.
Unfortunately, Google does not provide any tools or functions in its Android API to support the Wi-Fi ad hoc mode. As a consequence, we had to include some specific system-level code so that DoDWAN Apps can configure the Wi-Fi interface in ad hoc mode. This system-level code may not be very portable. You will rapidly know if it works correctly on your smartphone as it is called just after the application is launched. If it is not the case, you will have to abort the application or reboot your smartphone, with no induced side effects.
