[ns] I don't know how to load the scenario-file in probabilistic distribution !!!!!!

Dear Ns-Users,

Actually, I am trying to implement the " Probabilistic Algorithm in NS2".

The problem is; when I generate a scenario file in a randomly distributed nodes in the network, I give the scenario file a filename using ./setdest.

But when I run the simulation it tells me that it cannot readt the scenario file. So I am afraid that I miss something and do not know it indeed.

the syntax to implement the tcl script is:

Script usage is : ns pbcast_randsim.tcl -scenfile (scenario-file) -prob (probability) 

 I use the following when implementing:

tamer@zeid:~/ns-allinone-2.34/ns-2.34/pbcast$ ns pbcast_randsim.tcl -scenfile scen-20 -prob 0.6

and it gives me the following:

num_nodes is set 20
couldn't read file "scen-20": no such file or directory
    while executing
"source.orig scen-20"
    ("uplevel" body line 1)
    invoked from within
"uplevel source.orig [list $fileName]"
    invoked from within
"if [$instance_ is_http_url $fileName] {
set buffer [$instance_ read_url $fileName]
uplevel eval $buffer
} else {
uplevel source.orig [list $fileName]
..."
    (procedure "source" line 8)
    invoked from within
"source $val(scenfile)"
    (file "pbcast_randsim.tcl" line 113)

The defining options are the following:

# ======================================================================
# Define options
# ======================================================================
set val(chan)           Channel/WirelessChannel    ;# channel type
set val(prop)           Propagation/TwoRayGround   ;# radio-propagation model

set val(sc)"/home/tamer/ns-allinone-2.34/ns-2.34/indep-utils/cmu-scen-gen/setdest/scen-20"   ;# scenario file
set val(x)500.0   ;
set val(y)500.0   ;
set val(simtime)100.0   ; #sim time

 Could any one help please?

Thank you in advance.

Best Wishes
