hi
i am trying to run my tcl file based on mobileip,mpls and hierarchical addressing. whenever i run the file, i come accross the following output.
num_nodes is set 9
INITIALIZE THE LIST xListHead
Default value for cluster_num set to 4
Default value for nodes_num set to 5
Segmentation fault
what might be the problem, could someone figure it out. The code is as follows
Code:
set opt(chan) Channel/WirelessChannel ;# channel type
set opt(prop) Propagation/TwoRayGround ;# radio-propagation model
set opt(netif) Phy/WirelessPhy ;# network interface type
set opt(mac) Mac/802_11 ;# MAC type
set opt(ifq) Queue/DropTail/PriQueue ;# interface queue type
set opt(ll) LL ;# link layer type
set opt(ant) Antenna/OmniAntenna ;# antenna model
set opt(ifqlen) 50 ;# max packet in ifq
set opt(nn) 2 ;# number of mobilenodes
set opt(adhocRouting) DSDV ;# routing protocol
set opt(x) 400 ;# x coordinate of topology
set opt(y) 400 ;# y coordinate of topology
set opt(stop) 60 ;# time to stop simulation

This is the correct file without segmentation fault
