Hi all,
I have a code programmed in JAVA that i want to insert in NS2 module .
The problem is that i don't manage very well C++ . So i don't want to
reprogram it on C++ .
Is there a way to use JAVA script under NS2 ?
Thank you on advance

Dear all,
i need to comment the output file (alternative format) generated by
GT-ITM.(example of 4 nodes below)I can't see the direct link between vertices .
Also , i didn't understand the utility and meaning of the first bloc (VERTICES,
u v w x y z). In EDGES bloc, does lenght refer to
Hi friends,
I must measure the delay of a two-way traffic (like Voip traffic ) . In other
words i must measure the delay ( source , destination, source ) So i need that
the destination returns a reply packet as an acknowledgment to the source .
How can i create this packet ?? or is there an

Who has already generated a BI-DIRECTIONAL voip trafic ? I need a patch which
is sure and that has already worked for you .

Hi all,
I'm simulating GPSR protocol. I need to calculate delay through Timestamp in
real time during the simulation. So i need to add the timestamp field in the
GPSR packet header.
How can i add that ?

Hi Friends,
I have long simulations in a wide network and I need to free the memory after
allocating it.
i hear about the function Packet::free( ) like Packet::alloc( ) which is
already called in some protocol code ( AODV for example )
So how can i add this function if it's the true one?

Hi friends,
I'm simulating urban Vanet traffic . i have a correct
scenario file for real traces of the mobility that i found in a sure
site http://www.lst.inf.ethz.ch/research/ad-hoc/car-traces/. This is a short
par of the file :
$ns_ at 0.0 $node_(0) switch OFF ;# set_X,Y,Z
Hi NS users,
i just want to know who has simulated with the realistic Vanet traces from the
well known site
http://www.lst.inf.ethz.ch/research/ad-hoc/car-traces/index.html#download.
So i can ask him if the mobility trace file work well or not.
Thank you for the reply and good luck

Hi Friends,
This is the options related to a traffic generator whith which i must work in
my project :

Any one has an idea about the difference between : active nodes and
connections?
Thank you

Hi friends,
i'm simulating the GPSR protocol combined with the location service HLS .
the trace file that i obtainde has this format :

Hi friends,
I have a problem in the packet reception. All packet are dropped. The problem
isn't from the code because i work with a sure one. it maybe from the network
layer.
Any one can help me to know whether all the networks layers are active? Thank
you in advance.
Best regards,
zak
Hi friends ,
Any one please can send me some awk script for routing
performances. i'm simulating GPSR protocol and must evaluate these
parameters :
1.Packet delivery ratio
2.Traffic Overhead
3.End to End Delay
