ns: _o108malicious: invalid command name "_o108malicious" while executing "_o108malicious" - tcl

Question

I am simulating Wireless Sensor Network Using NS2.35 and I get an error
ns: _o108malicious: invalid command name "_o108malicious"
while executing "o108malicious"
when i add $ns at 3.2 "[$node($id) set ragent_]malicious"this line i get
this error.

Answer 1

When the "set malicious" line $ns at 3.2 "[$node_($id) set ragent_]malicious" ... is edited to $ns at 3.2 "[$node_($id) set ragent_] hacker" ... then your files are working fairly OK :
$ ns235-malicious mal-wsn.tcl
num_nodes is set 25

channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5, distCST_ = 550.0
SORTING LISTS ...DONE!
ns: scheduler going backwards in time from 6.000000 to 0.000000.
The files aodv.nam 200.0kB, aodv.tr 184.0kB are created. $ nam aodv.nam & : OK animation and communication. $ awk -f tess-Packets.awk aodv.tr : OK, the output file "Packets-arrival-time.txt" has 338 lines.
Not quite stable. Can also end the simulation with
SORTING LISTS ...DONE !
Direction for pkt-flow not specified; Sending pkt up the stack on default.
... And NAM opens OK. The files are now: aodv.nam 328.0kB, aodv.tr 308.0kB .
Perfect. Ends with SORTING LISTS ...DONE!. Animation: Perfect. Files are aodv.nam 7.0 MB, aodv.tr 5.7 MB .
Direction for pkt-flow not specified; Sending pkt up the stack on default.
check_pktRTS:Invalid MAC Control subtype
... Conclusion : You will have to run the file several times to get a perfect result. Can be 10 times if Ubuntu. 3 - 4 times if an rpm based OS.
