Hi all ,
I am new to NS-2(im using ns-2.28 an ns.2.30).I am trying to include Ricean
propagation model
with the following steps:
1-Copy the two files under ns-src(prop-ricean.cc,prop-ricean.h) into my NS
source directory
2-edit Makefile.in in my NS source directory and i added the
mobile/prop_ricean.o \ to OBJ_CC
3-Run configure
4. make clean
5. make
but when I am trying to test the Ricean propagation model using the following
code I got the
following error:
num_nodes is set 10
invalid command name "Propagation/Ricean"
while executing
"Propagation/Ricean create _o13 "
invoked from within
"catch "$className create $o $args" msg"
invoked from within
"if [catch "$className create $o $args" msg] {
if [string match "__FAILED_SHADOW_OBJECT_" $msg] {
delete $o
return ""
}
global errorInfo
error "class $..."
(procedure "new" line 3)
invoked from within
"new $propType_"
(procedure "_o3" line 29)
(Simulator node-config line 29)
invoked from within
Here is the code portion related to the error:
