[ns] Blackhole attack
Hi, I am modifying dsr to counter blackhole attack. If anyone have simulation of Blackhole attack please send me. Thanks in advance, subhash.
[ns] MANET - Black Holes
Hello everyone, I am doing a simulation project similar your work on intrusion detection in MANET ...In my project, I've focused on DSR and Black hole attacks ... Does any one HAVE or ACCESS to modified agent and other resources of Black Hole attack?(e.g. modified DSRagent.cc and DSRagent.h ) or even related TCL sample file ...I will highly appreciate you if you send me resources of Black Hole ... Thanks in advance, regards, subhash.
[ns] A simple umts scenario
hello,
I have patched ns-2.28 with EURANE. I wanted to test the UMTS link but
my code seem to contain some error. UE, node 2 in my case, is not
connected as visible in nam even though I have created a DCH channel.
Can anyone give a hint what could be wrong in the following script.
Thank you in anticipation. cheers,
Luqman

[ns] [Help/Query] error when running tcl code for a new routing protocol implemented
Hi nsusers,
I have implemented a part of a hybrid routing protocol for adhoc networks. I
have written the code for the neighborhood discovery and the local routing
protocol. I just wanted to check if my code was working alright, therefore i
wrote a simple tcl script which has 2 node, i make sure that the nodes are close
to each other so that they can communicate with each other.
The problem is that when i run the ns command i get the following errors:
I cannot understand why i am getting these error or where i am going wrong.
Please could anybody help me with these errors.
thanks in advance.
cheers,
Melvin

[ns] Mash Inspector on Mac OS X
Hello All, I've recently patched my installation of ns-allinone-2.29 (running on Mac OS 10.4.7) to use the Mash Inspector, but I am experiencing very poor performance. Is anyone else using Mash on Mac OS X? Thanks! Brad
[ns] TKN Model 802.11eand wireless Error Model
Hi NS users, I have a problem with 802.11e Model of TKN of Berlin. If I set an Error Model for the wireless channel using Mac 802.11e, no one packet is dropped in the trace file. If I use the same simulation just changing MAC 802.11e with MAC 802.11 I see that some packet get lost in the wireless channell. Does anybody knows how to use Error Model with 802.11e Model? Thanks a lot, Michele Nuti
