invalid command name “Agent/LeachAgent”


I try to implement a simple scenario for LEACH protocol but I get this error:

Creating Sensors ... invalid command name "Agent/LeachAgent" while executing "Agent/LeachAgent create _o2340 " 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 $..." (procedure "new" line 3) invoked from within "new Agent/LeachAgent" ("for" body line 3) invoked from within "for {set i 1} {$i <= $val(nsn)} {incr i} { set agent($i) [new Agent/LeachAgent] $ns attach-agent $node_($i) $agent($i) $agent($i) set packetSize_..." (file "newleach3.tcl" line 187)

I use ubuntu 16.04 and ns-allinone-2.35 . when I ran my tcl file for the first time, i did not get this error.


Change your script to use Agent/RCAgent/LeachAgent as class name:

set agent($i) [new Agent/RCAgent/LeachAgent]

From what I can see, there is no Agent/LeachAgent in ns-allinone-2.35.


I was not successful in writing a correct code for attaching Leach protocol in my scenario, but I found that mannasim has a Mannasim Script Generator (MSG). It is a front-end for TCL simulation scripts easy creation.
