A design decision like this can be accepted if it was supported by
proper documentation, which is absolutely not the case for ns-2. IMHO,
the biggest problem of ns-2 is lack of proper documentation.
At least, there has to be two documents: a user's guide, and a
developer's guide.
ns manual is,
Hi all,
Could anyone tell me how to calculate routing overhead of DSR?
How about the header size of RTR ( DSR ) and MAC (802.11) ?
"
s 18.741626845 _1_ AGT --- 681 cbr 10 [0 0 0 0] --- [1:0 0:0 32 0]
[679] 0 0
r 18.741626845 _1_ RTR --- 681 cbr 10 [0 0 0 0] --- [1:0 0:0 32 0]
[679] 0
OK,
I don't need remove the headers.
But I didn't understand L3 header and L4 header. What's that?
AODV / DSDV: 1060 bytes. (TCP 1000 + IP 20 + "??")
DSR: 1040 bytes. (TCP 1000 + "??")
Can you help me?
Virginia.

Hi,
You need change this parameter: "set opt(ifq) Queue/DropTail/PriQueue".
Change to "set opt(ifq) CMUPriQueue"

Hi,
In this case, you need to use a debugger such as gdb to find out where is
the problem.

Hi,
IMHO, the mixture of C++ and oTcl is the most annoying feature of NS
which makes it really hard to understand the code.

Hi, all,
The following "Bug Fix"

Hi Virginia,
In ns-2 the default packet size is 1000 bytes. In AODV and DSDV the
default MTU is 1060 because of the L4 header (20 bytes) and L3 headers
(IP 20 bytes and AODV[DSDV] another 20 bytes). In DSR there is no IP
header, that's why the packet size is 1040.
In TCP, if you want to change
Sven, Ethan thank you.
I managed to build ns2 from package ns-2.29.3, but it did compile only
when I tried to install it from an X client.
nam compiled fine.Everything is OK now!!!
Thank you!
Hi !!!

Just a tiny hint..
When you trace the code, don't forget that ns-2 is a mixture of C++ and
oTcl. Much of the object passing is done through oTcl.

Hello Ns-users:
I have doubts about the implementation of the timers because there are two
forms.
In AODV, they use:
class HelloTimer : public Handler {
public:
HelloTimer(AODV* a) : agent(a) {}
voidhandle(Event*);
private:
AODV*agent;
Event intr;
};
Hello everybody!
Can anyone tell me how to install fhcf or afedcf implementation to NS-2? Can
anybody help?
I tried './make install' command in ns/ns2 directory but it doesn't work.
In which directory should I unpack this implementation? Do I need add it to my
already installed ns-allinone-2.2
Hi everyone,
I'm simulating a ad hoc network with 50 random mobile nodes ... and 15 random
CBR traffic ...
The simulation is successful under AODV protocol;
but when I just define DSR routing protocol for same network, it FAILS with
following ERROR:
Segmentation fault

Hello,
I'm using FTP with TCP, and would like know the packet size.
In the my simulations, I'm using three types routing protocols. (AODV, DSDV and
DSR). Are the size packets
differents? With AODV and DSDV the packet size is 1060. And DSR the packet size
is 1040. Why occurs that?
Regards.

The allinone 2.29.3 package compiles fine (with the exception of nam)
on OS X 10.4.6 running on Intel Core Duo.
The 2.29.3 package was a maintenance release announce a few days ago.

Hello everybody!
i have written before about the failed TORA simulation, but i haven't found
any solution for my problem.
Does anyone have an example of a TORA simulation that works? Please, this is
essential for my project. Anything would be useful.Thank you in advance!
