[ns] EXEC error????
Hi,
I try to execute this tcl script:
set maxDist 15
set stepDist 2
set maxVel 20
set stepVel 2
set xDest 14
for { set i 1 } { $i $maxDist } { incr i } {
#uso tcp_bt_df.tcl DISTANZATRAINODI
puts TCP OVER BT DISTANZA FISSA: $i metri
exec ns tcp_bt_df.tcl $i
}
and i have this error:

I'm sure script TCL tcp_bt... is correct!
Thank u in advance,

Re: [ns] EXEC error????
Hi Pietro,
Here is my suggestion. If you are sure that tcp_bt.tcl is correct,
try to run the following
ns tcp_bt.tcl 1
ns tcp_bt.tcl 2
ns tcp_bt.tcl 3
...
Keep changing the last number until it hits 15.
Does it create any error?

[ns] segmentation fault while calling getLoc function(getting node position)
Hello, I need to get the current position of the node during the simulation, so I added in the cc file: double ox,oy,oz; MobileNode * otherNode; otherNode = (MobileNode *)(Node::get_node_by_address(id)); otherNode-getLoc(ox,oy,oz); but I have a segmentation fault at the beginning of the simulation. Can you help me please to solve this problem ? Is there any other method to know the current node position? Thanks
[ns] Is Agent::recv(Packet* p, Handler *) called only when a BroadcastPacket o a packet whit his address is come to an Agent?
I have a configuration like this: node($i) attach-agent MyAgent($i) [$i from 1 to 3] $ns connect MyAgent(1) MyAgent(3) [only for this Agent] n1n2-n3 In my wireless simulation, n1 is out of the range of n3, but n2 is in both ranges; then with the AODV routing algo, n2 forwards all the pkt from n1 to n3. The question is: When n2 receive this kind of packets (n1 --- [n2]---n3) the method Agent::recv(Packet* p, Handler *) isn't invoked There is another method in class Agent or a way to access at this Packet* p? PLEASE, i need your help!!! Thanks in advance!! --- Francesco Salpietro

[ns] Ping packets not recieved in wireless simulations
Hi,
I have encountered a problem while using Ping protocol. While the protocol
works file when used in wired simulation, for some reason, it fails for
wireless. In case of wireless, the recv() function of the protocol is not
called at all.
Can somebody point out the reason for this.
I have included the TCL scripts for both wired and wireless case.

[ns] Segment fault
Hi . when i am running a tcl script i got an error segment fault. i am run the simulation for 10 nodes it's run sucessfully. when i am trying to run simulation for 20 nodes at the end of simulation it gives an error segment fault . plese help me thank u an advance
