Hello,
I have been able to implement the Manet routing protocol (protoname). I have
got it to compile successfully but when i run a test simulation using it , i
do not get any packets to be successfully transmitted. I printed out the
routing table onto the trace file and noticed that the routing table is
empty throughout the simulation. The same simulation file works fine when i
use AODV or DSR for that matter.
I am not sure why its not sending any packets.
i did not get any errors when compiling protoname.
here is the simulation script.
the trace file for this is available at www.ece.utk.edu/~njha/out_fixrt.tr
any help would be greatly appreciated.
