Segmentation Fault in NS2
Hi Friends …
My friend who are using NS2 specially Ad-Hoc Simulation they sometime got this problem
“Segmentation Fault ” arun@Merom:~/myNS2/Assignment/Wireless$ ns wireless-tcp1.tcl
num_nodes is set 8
warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl
INITIALIZE THE LIST xListHead
Starting Simulation…Sir !!!!
channel.cc:sendUp – Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5, distCST_ = 550.0
SORTING LISTS …DONE!

Segmentation fault
I have a solution for that please go through this post and you will be happy ..
actually this segmentation fault problem happens due to “DSR” Ad-Hoc routing table when we are using any type of queue with DSR routing Algo . so CMU made a “CMUPriQueue” to deal with that so please follow that code …..
if { $val(rp) == “DSR” } {
set val(ifq) CMUPriQueue
} else {
set val(ifq) Queue/DropTail/PriQueue
}
so there will be no segmentation fault ….
Enjoy please like it … if your problem is solved .
