[ns] Segmentation Fault in DSR
Hello,
I am working with ad hoc protocols in point-to-multipoint and
multipoint-to-point scenario with 1, 2, 5, 10, 20 and 50 nodes. The
simulation take 1020 seconds.
With few nodes, there is no problem. But with 20 and 50 nodes, the
segmentation fault occurs with 400, 600, 800 seconds. Anybody has any
idea?
I am appending a shell script file and the TCL file.
Thanks in advance.

The only time that I have seen DSR to generate a segmentation fault is
when you define a queue type other than CMUPriQueue. which in your case
you should be fine.
can you send us the exact error?
Thanks,
Sasan

Hello,
I am working with AODV, DSDV and DSR in point-to-multipoint and
multipoint-to-point scenario with 11 nodes.
In the multipoint-to-point scenario, the senders starts a CBR traffic to
the receiver with 1 second interval and, after 11 seconds, as expected,
there are 10 simultaneous flows.
The problem occurs in the point-to-multipoint scenario. The sender starts
a CBR traffic to all receivers with 1 second interval, so after 11
seconds, there supposed to be 10 flows from the sender to the receivers,
but in fact, there are only 3 simultaneous flows. Does anyone know the
reason?
I am appending a shell script file and the TCL file.
Thanks in advance.
Etienne Oliveira.
