Hello,
I successfuly installed ns2.34 on a MacOS(Lion). My Mac is a (Core i7-64bit
processor). When I execute ./validate and these tests fail:
validate overall report: some portable tests failed:
./test-all-newreno ./test-all-sack ./test-all-tcpOptions ./test-all-tcpLinux
Hi all,
I've downloaded ns-allinone-2.35 and extracted into the directory
/Users/username/ (where username refers to my username on my Mac).
Then, I run ./install and it fails to build OTcl-1.14, as you can see below:

simulations if I these models do
not work properly on my machine?
Thanks in advance for your reply,
Kind regards,
Behnaz

Do you have a code example or implementation
Hi,
I do not know anything about SMAC, but usually if you have a
UDP agent connected to your CBR application, the
fragmantation is done by UDP. So, a UDP packet is by default
1000 bytes. if your CBR sends less than 1000 bytes to UDP,
the CBR bytes are put in one UDP packet and the packet is
sent

Hello,
I would like to calculate transmission time (tx_time) for packets sent by CMU

Usually we have tx_time=packet size/channel bandwidth.

Is this the value used for calculation

Hi all,
As I checked in mac-802.11.cc, it seems that interface queue only sends one
packet at a time to MAC 802.11 (but i am not 100% sure) and it waits to dequeue
and send the next packet to 802.11 MAC until a callback is triggered by
mac-802.11.
So the call back is triggered by mac-802.11
you to study how
Mac802_11::txtime(double psz, double drt) function works
in mac-802.11.cc
Good Luck.

1) Please send your questions to the ns mailing list and not only to a specific

2) There was a whole discussion regarding this problem in the mailing list, so
I do not know which part of the discussion you have found,

As far as I understood we can use the shadowing propagation model for wireless

Hello all,
I read somewhere that most network cards use multirate only in unicast mode and
for broadcast they use only the basic rate (i.e., 1 or 2 Mbps in 802.11b/b+g,

Is it the case if in dei80211mr-1.1.4/nsmiracle implementation.
