[ns] Urgent: Bandwidth allocation in wireless ad hoc
Hi I am working on wireless ad hoc networks. I have simple scenario in which one node is sending packets to other. I set packet size 512 bytes and interval between each packet is 0.0025. it means application layer (CBR) generate total 1/0.0025 = 400 packets in a second. Each packet is 512x8 = 4096 bits (512 bytes). It means application layer is generating 1.6384 Mbits per second. I have set, Mac/802_11 set bandwidth_11Mb Mac/802_11 set PreambleLength_ 144 Mac/802_11 set PLCPHeaderLength_ 48 Mac/802_11 set PLCPDataRate 1.0e6 Mac/802_11 set dataRate_ 20M Mac/802_11 set ShortRetryLimit_ 7 Mac/802_11 set LongRetryLimit_ 4 Mac/802_11 set MinimumBandwidth_ 11mb === Sending application layer is generating packets at rate of 1.6384 Mbps but receiver is getting data at rate of just 0.7 Mbps, which is very less, almost half. Interesting thing is that when I change Mac/802_11 set PLCPDataRate 1.0e6 to Mac/802_11 set PLCPDataRate 11.0e6 because I need total 11 Mbps bandwidth. this throughput increases from 0.7 to 0.8 Mbps but still not 1.6384 Mbps. would be greatly thankful to you If anybody solve my problem.

Re: [ns] (hier-rtg-100.tcl) doesnt run!?
If that script is not in /tcl/test, it is not part of the standard test
suites, and thus it can be outdated.
Try to find the equivalent script (for hierarchial tests) in this directory
that is guaranteed to run
Also, check

[ns] Node add/removal processes in nam
Hi to all ns-users, Though a newbie in ns, I already find out that it is a very powerful simulation tool! Thanks to every ns-developer! What I wanted to ask is whether the nam visualization tool can support (display) node add/removal processes. To be more specific, by encorporating an energy model in my 802.15.4 wireless sensor network, wireless nodes will stop operating once their energy is expended. What I need therefore, is to visualize the above node failure process and see how the network behaves around these "dead-zones". Is that possible? I would be pleased if you provided me with any code (or hints) dealing with the above processes. Thank you all in advance. Irini
[ns] [urgent][help] How to add a value at the end of each row of the wireless trace file.
dear all; In my simulations, i want to make some modifications in ns code (C++ or Tcl) in order to add an other entry to my trace file. i explain more, i'm simulation an Ad Hoc network (802.11) using ns. in order to study the contention window (CW_) of backoff procedure i need to trace this variable, that is implemented but not binded, in the trace file when collisionis made. i want to add at the end of each row in the wireless trace file the value of CW_. thanx in advance. please help me it's urgent, and the deadline will after some days. - Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !

[ns] need urgent help about mobile node movement in nam
hello!
how to visualize the movement of the mobile node in nam? after
the creation of the nodes.on has exchange their positions with the command:
*$noeud($i) set X_ valx
$noeud($i) set Y_ valy*
and it works but it is not visible with the level of the nam then one
tested with the order :
*$ns at [$ns now] "$noeud($i) setdest valx valy vitess"*
and the following error was received:
ns: _o10 setdest 50 20 9:
(_o10 cmd line 1)
invoked from within
"_o10 cmd setdest 50 20 9"
invoked from within
"catch "$self cmd $args" ret"
invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
(procedure "_o10" line 2)
(SplitObject unknown line 2)
invoked from within
"_o10 setdest 50 20 9"
one tried to make :
*$ns at [$ns now] "$noeud($i) set X_ valx"
$ns at [$ns now] "$noeud($i) set Y_ valy"*
**
that does not work also then please help us it's urgent. how to make it? if
you can sent to us to make a script of creation of a node and it change
position and that is visible in the nam.

[ns] How "really" change transmission range
Hi all, I have a problem in a wired-cum-wireless scenario: in my scene, there are 4 Base Station that make a square. The distance betwen 2 BS is 1000 m. I want the transmission range of every BS to be 750m, so that a mobile node doesn' t lose packets when passes from a BS to another. I tried to modify the RXthresh_ parameter in the Phy/WirelessPhy field, according to the program threshold.cc, but in the simulations nothing changes: The mobile node begins to lose packets 200 m past the BS and resumes the connection 200 m before the next BS. In some cases, it resumes the connection 10 m before the BS. So the mobile node moves for 600 to 800 m without a connection and all the packets drop. Then i tried to modify the Pt_ variable. I put it to 1.0, 2.0 and also 20.0. It doesn' t change anything. Then I tried to modify txPower and rxPower of the BSs, I put them to 1000. But nothing changed. So I surrender to the idea that in ns2 the transmission range cannot change. If someone would show me that I am wrong, I would be much obliged. Thanks in advance!

hello frnds, in simple tcl script if we are using cbrgen.tcl for speed of the node and max .connection after that ..it wil not generate a connection as we specify in cbrgen.tcl ..why it is happening?if we specify 8 conn. enenthough it will generate 5 conn. so is that conne.acually created or not? khushali shah - Heres a new way to find what you're looking for - Yahoo!
