I am trying to implement the following scenario where I have 3 nodes, A, B and C:

At time t1 = A and B dtnd daemons are active and C is inactive. A sends a message to C C. So, it forwards the bundle to B.

At time t2 = B and C dtnd daemons are active and A is inactive. B forwards the bundle received  from A to C.

I tried implementing this through dtnsend/dtnrecv. I notice that A does not send message to B even if I configure epidemic routing.  DTNSEND from A to C gives an error that TCP connection refused. I have read the documentation but it is still unclear as to how can I implement this. I am attaching the configuration with this email.

I have olsrd2_static as the routing agent in the background.

Any help would be appreciated!
