[ns] adding multi-channel supporting based on aodv
hi all,
I am working on Adding Multiple Interface Support in NS-2 available on
ttp://personales.unican.es/aguerocr/ based on AODV .My question is that
sending a unicast packet.which interface should send to ?
listing 5.4
if(nIfaces)
{ Scheduler::instance().scheduler(,targetlist[nIface],pkt,0,) }
else
{ Scheduler::instance().scheduler(,targetlist,pkt,0 }
listing 5.5
if(nIfaces)
{
Iface=cmn-iface()-((Mac *)ifqueuelist[0]-target())-addr();
}
else
{
Iface=-1;
}
I set nIface as a member of AODV::sendReply(),and add listing 5.4 ,5.5 in
AODV::sendReply,but when I make ns,
It gives me error information: cmn is not defined! why?
any help will be appreciation!

[ns] how to solve segmentation fault in ns2
hello all,
I am working on add multi-interface multi-channel support in ns2 ,but now I
meet a segmentation fault in implementing adding Multiple Interface Support in
NS-2, I use command :
$gdb ns
$r channel.tcl
$bt
it gives reminding information as follows:
#0 0x081112a7 in WirelessChannel::sortLists ()
#1 0x08112269 in WirelessChannel::sendUp ()
#2 0x08110e3a in Channel::recv ()
#3 0x0813494b in WirelessPhy::sendDown ()
#4 0x08132d9d in Phy::recv ()
#5 0x0805b4de in Connector::send ()
#6 0x08139781 in CMUTrace::recv ()
#7 0x0811980f in Mac802_11::transmit ()
#8 0x08116110 in Mac802_11::check_pktTx ()
#9 0x08116350 in Mac802_11::backoffHandler ()
#10 0x081357f4 in BackoffTimer::handle ()
..
Now I think segmentation fault is caused by WirelessChannel::sortLists (),but I
can not find practice reasons, please help me!
another question is Simulator instproc add-channel { indexch ch}
{
$self instvar chan
set chan(indexch) $ch
}
when i run test.tcl ,It always gices me that variable is not array.
please help me
thanks a lot !

Dear all, Now I meet a tough problem that I can not configure ns . when I run ns in command line prompt. It gives me that information : When configured, ns found the right version of tclsh in /home/wjw101/ns-allinon e-2.30/bin/tclsh8.4BRbut it doesn't seem to be there anymore, so ns will fall back on running the fir st tclsh in your path. The wrong version of tclsh may break the test suites. Rec onfigure and rebuild ns if this is a problem.BR% I can also run TCL script, but when i modified the *.cc and *.h file and run make make depend make command, I find that modification does not work , I do not konw why it is. my system configuration is that: intel cpu , fedora core 5 linux, ns-2.30 .

Dear all, I want to simmulate Csma/ca used in 802.15.4, but I do not know how to start, I do not konw how to count the number of collision, when to start collision, I think collision can only start when more than two nodes send data to a node at the same time, another question is how I can change CW, BE and NB in source code .so that another question is how I know what I simulate is Csma/ca.
