Hi all,
I am facing a problem in the used traffic scene within my ad hoc
network. My objective is to have only 5 active connections at the same time
where each connection has lasts for 40sec. below there is a part of
the used traffic scene. The problem is when cbr_(2) stops a segmentation
fault is generated and the simulation stops. Can any body tell me why?
Thanks in advance,
Ghada
