Re: [ns] simple question about node direction and speed

I'm not sure if the node in ns2 can know its direction and speed at any time It is up to you to specify the mobility model to pretend the speed, direction and therefore the moving behaviour. Ask google before you type you questions here - nobody will do your homework!

Re: [ns] important: TCP packet size
Use the following code: # setup a tcp connection across the n8-n18 link # create a new tcp agent called tcp818 set tcp818 [new Agent/TCP] # Set the source to be node n8 $ns attach-agent $n(8) $tcp818 # create a new TCP sink agent called sink set sink818 [new Agent/TCPSink] # set the sink to be node n18 $ns attach-agent $n(18) $sink818 # establish the TCP link between node n8 and node n18 $ns connect $tcp818 $sink818 # this assigns a flow indicator so flows can be distinguished in NAM $tcp818 set fid_ 3 # this sets the packetsize to 1460bytes, the default is 1000bytes. $tcp818 set packetSize_ 1460 # define an CBR application to go across CBR link cbr818 set cbr818 [new Application/Traffic/CBR] $cbr818 attach-agent $tcp818 $cbr818 set packetSize_ 1460 $cbr818 set rate_ 200Mb $cbr818 set random_ false I have been using CBRs for most of my TCP testing, however if you wanted to use FTP then the following code should replace the CBR section: set ftp818 [new Application/FTP] $ftp818 attach-agent $tcp818 I don't know if it's necessary to set the packetSize for TCP and CBR, however seeing as there was the option I thought it was safest! Anyway... it appears to work. There is something worth noting however, in the trace file the file size will be 1500, as this is the total size of the IP packet. Hope this helps!

[ns] energy model variables
Hi all
I am trying to access the value of the initial energy for the energy model
after configuring the nodes. for example after
$ns_ node-config -adhocRouting $val(rp) \
-llType $val(ll) \
-macType $val(mac) \
-ifqType $val(ifq) \
-ifqLen $val(ifqlen) \
-antType $val(ant) \
-propType $val(prop) \
-phyType $val(netif) \
-topoInstance $topo \
-agentTrace OFF \
-routerTrace OFF \
-macTrace ON \
-movementTrace OFF \
-energyModel EnergyModel \
-initialEnergy 3 \
-rxPower 0.3 \
-txPower 0.3 \
-IDLE 0.3 \
-channel $chan_1_
#-errProc UniformErr
#-IncomingErrProc UniformErrorProc
#-IncomingErrProc $val(err)
for {set i 2} {$i $val(nn) } {incr i} {
set node_($i) [$ns_ node]
$node_($i) random-motion 0 ;# disable random motion
}
I want to check the initial energy using an if statement
if {$initialEnergy 2} { DO WHATEVER}
I will be grateful for your help

[ns] run 802.11b in ns2
Hi all, if i want to run 802.11b(11Mb) in ns2, do i just need to make the following changes: Mac/802_11 set bandwidth_ 11Mb Mac/802_11 set dataRate_11Mb Mac/802_11 set basicRate_ 2Mb or do i also need to change the bandwidth of the physical layer Phy/WirelessPhy set bandwidth_ 11Mb should anything else be modified too?

Re: [ns] Application Layer Payload Transfer
* Sidney Doria | 2008-04-23 13:05:59 [-0300]: We know that NS-2 Transport API to Application layer does not provide a payload transfer. In NS, Transport only tells to the application: hey, a packet with nbytes has arrived. But no data is transfered to the app. I'm using UDP and I need the payload to simulate well my application's behaviour. *** How did you, hard core people, circunvent this issue? You must extend the frame structure and add an additonal field for payload. Grep the source and you will find frame extensions where people add additional QOS flags or piggybacking other information as well. Not that big issue! And... Why NS2 does not provide this?! Why should provide NS2 this? Nobody (except you) need this feature. In the normal case the payload isn't interessing. HGN
Re: [ns] Not receiving data packets at agent.
Hi Maddy, On Wednesday 23 April 2008 03:55:47 Madhava N wrote: Hi all, I have written a new MANET routing protocol by reading the document of Franscisco and Pedro. I am facing a problem that data packets are not at all received by the routing Agent. The routing protocol does not receive the packet when the attached node is its destination. Quickdirty workaround: put the node in promiscuous mode in order to process every packet which arrives at the interface (see Tap). That is at recv() function it is only receiving the HELLO (defined by me) packets. But the recv function is same as OLSR or AODV or DSDV which receives data packets as well. Also, I noted that if-queue parameter which i have used is never set. What could be the problem that I am unable to get the data packets at all. Because you are not invoking if-queue from TCL. See add-target in tcl/lib/ns-mobilenode.tcl. Regards, fran Any help is greatly appreciated. Regards, Maddy .
[ns] Ask Google is not a polished answer, isn't it?
Herr Hagen Pfeifer, NS2 is not easy to novice. It's normal that novice people be confusing with some questions and concepts, even network concepts. After months same people that have asked a foo question are now secure, with strong skills and helping another novices with their new foo questions. I was a novice in past, with foo questions and now a I'm a non-novice with less foo questions. My first multicast routing protocol for MANETs is done! Great! Thanks to people that have patience to respond my foo questions with courtesy. Don't do that with NS2 people. NS2 is hard enough. PS.: I'm not talking about your answers to me.

[ns] DSDV packets
Hi, All. Does anybody know how to distinguish a DATA packet from a CONTROL packet in DSDV routing protocol for MANETs? For example, I know that in AODV implementation all packets with 'ptype_' equal to PT_AODV are CONTROL packets.

[ns] New PUMA version
Hi NS-all, I've just uploaded a new version of Puma to sourceforge at sourceforge.net/projects/puma-adhoc. Now puma.zip has a .tcl and scenario files. Puma is a multicast routing protocol more efficient than MAODV and ODMRP. Puma was designed by Ravindra Vaishampayan and implemented by me on NS-2.
