hi ns experts,
Sorry for repeating this question.=20
It is most urgent to complete my simulation.
I am doing little research by using ns-2.1b7a on Linux machine.
I tried to build Error Model in wireless simulation but it gave me =
error.
The following are the model and the error=20
I would appreciate your help very much
Thanks
THE BASIC MODEL:
source ns-errmodel.tcl
set emm [new ErrorModel ]
$emm unit pkt
$emm set rate_ 0.2
$emm ranvar [new RandomVariable/Uniform]
$emm drop-target [new Agent/Null]
$ns_ lossmodel $emm $node_(6) $node_(7) =20
THE ERROR:
invalid command name ""
while executing
"$link errormodule $lossobj"
(procedure "_o4" line 3)
(Simulator lossmodel line 3)
invoked from within
"$ns_ lossmodel $emm $node_(6) $node_(7)"
