Hi folks,

I am executing some experiences with IBR-DTN in a mesh network. My setup is as follows:

PC 1 ———————— Router 1 ——————————— Router 2 ——————————— PC2

Routers 1 and 2 have two wireless cards, one of 2.5 Ghz (wlan0) and one of 5 Ghz (wlan1). The routers are connected together by wlan1, which operates in ad-hoc mode. PC1 and PC2 are connected to the routers by wlan0, which operates in AP mode.

I installed IBR-DTN in all nodes. For PC1 and PC2, ibrdtnd runs on interface wlan0. For Router 1 and Router 2, ibrdtnd runs on both interfaces (wlan1 and wlan0). All nodes were configured with flooding routing policy.

In the aforementioned setup, I tried to send a file from PC1 to PC2 using dtnsend and dtnrecv, but the file never reaches PC2. I can ping PC2 from PC1 correctly, When I try the same experiment but between two nodes in the same network it succeeds. So, I`m wondering if the presence of two wireless cards in the routers is causing the problem.

Could you help me?

Best regards,

Igor.
