[ibr-dtn] Queries with IBR-DTN

Hello all, I am a student at Missouri University, USA. I have been doing research on DTNs and came across IBR-DTN. I found the paper really intriguing.

I have been using the applications IBR-DTN and ShareBox on Android and I found that it uses only wi Fi for connection. I know how it uses wifi router as a storage device. I have three questions as follows and any help on these will be highly appreciated.

1)Will I be able to use Bluetooth for this, atleast only for android? 2) If yes, will it be easy to do development for Bluetooth? 3) Also, does it have multi hop feature as well?

Thanks and regards, Himanshu Jethawa, Computer science, Missouri University of Science and technology, Rolls-MO, USA.
