Hi all,
Has anyone worked on wireless atm's in ns-2.28.
Does ns-2.28 have in built support for it? If not
atleast can anyone tell me if there are any patches
available in ns-2.28 or any other version for wireless
atm support. Thanks in advance.
with regards

Hi,
I would like to ask regarding trace file.
I need to calculate "Average End-End Packet Delivery Time".
This mean that for each packet with id (Ii) of trace level (AGT) and type
(cbr), I have to calculate the send(s)time and receive (r) time (t) and average
it.
I used g
hello all,
in a program to perform wired emulation i am getting the output as
below. i am not able to understand the meaning of cc, writing to
target, linked sock etc. any help will be appreciated.
When configured, ns found the right version of tclsh in
/root/ns-allinone-2.29/bin/tclsh8.4
Hi,
Do you mean by mobility the speed of a mobile node?
In this case, considering that -m and -M are the options to specify the
minimum and maximum speed of nodes (I don't remember well setdest options),
then setdest will dynamically assign to mobile nodes speed values ranging
from 1 to 6 m/s. If
Hi Faisal,
There's two possibilities to do that in ns. May be, in the examples
you are referring to, source and destination agents responsible of
generating packets are explicitely connected to each other in the tcl
script, making one of them source of packets and the other its
destination for all

Hi all,
I ran an example simulation using the main.tcl that is provided with ns2.
on line 239 (more or less) there is the following
for {set i 0} {$i < $num_bss_nodes} {incr i} {
$node_($i) setMac bss_id $AP_MAC
}
...
create_scenario
I used simple printf to know when mib constructors are bei
The way I calculate the overall simulation avg end-to-end delay is the SUM
of all transmission time framce within the whole simulation (end - start
per flows/packet ids) over total number of data packets received.
start[packetid] = time
end[packetid] = time
and for all packets
(sum of all end
I am doing a class project on ns2 - wireless flooding. Is there any
freely available tool to read the trace files? Thanks,

PS:- I did try the tracegraph 2.02 version but it gives errors and
doesn't work.
Hello,
I am running some QoS simulations in NS2 but unfortunately I can only see the
results for 802.11b which is becoming less and less popular. I was wondering
if there any 802.11a PHY layer implementation out there for NS2. I can't seem
to find any. Maybe I am looking in the wrong places.
Hello,
I have the following experiment. I need to send copies of packets from
one source to one destination along multiple links. I would like to
control which links to send the packets on (rather than use multicast or
replicator). The source and destination are not directly connected and
are
Hi,
I've been trying to implement a circuit-switched network model using ns-2 for
some time.
I have the following ideas:
- use manual routing and separate queues for each flow
- add path information to a packet payload
- lay more links between a node pair
- implement source routing
- implement
hi,
i suggest u to use
$ns_ use-newtrace
in your tcl script...the new format is quite easily understandable.
im assuming ur working in wireless and u have latest ver of ns-2.
hope this helps,

hi,
i guess you can use something like this
Agent/DSR set pbw [Phy/WirelessPhy set bandwidth_]

in your simulation (.tcl) file.
Now you can access this from your .cc file as follows:
