Hi,
You must have the mnode_ variable really pointing to the mobile node
associated to that agent.
For example for me, I defined a tcl command that I called "node" that
get's the node associates with the agent.
I added the following to the "command( )" method of my agent :
if (argc == 3)
if(strcmp(argv[1], "node") == 0) {
mnode_ = (MobileNode*) TclObject::lookup(argv[2]);
if(mnode_ == 0)
return TCL_ERROR;
mnode_ is declared as MobileNode * in the .h file of my agent.
Then in my tcl script, after creating nodes and agents, I can do :
for {set i 0} {$i < $opt(nn) } {incr i} {
set node_($i) [$ns_ node] ;#nodes creation
}
for {set j 0} {$j < $opt(nn) } {incr j} {
set clagent_($j) [new Agent/Clustering [$node_($j) node-addr] ]
;#agent creation
$clagent_($j) node $node_($j)
}
Hope it's clear.
Bye.
