[ns] how to start $cbr1 from classifier.cc
hi to all..
here i have to start the traffic on a condition from classifier.cc recv
function as shows below.. the time also i cant expect...
void Classifier::recv(Packet* p, Handler*h)
{
if ((node-id==_o27) (ready==1))
{
if the condition satisfies i have to start the traffic; but for the
command in tcl ($ns at time $cbr1 start )
here i don't know the time.. i have to start traffic if the condition
satisfies. and stop the traffic after 200milliseconds
}
please help me regarding this...
[ns] How to change transmission power of a specific node in the middle of simulation run time or in protocol?
Hi all, I am try to change transmission power of each node according to some parameters in my protocl, How can I set and adjust a node transmission power in simualtion run time? I know threshold -m propagation-model [other-options] distance and Phy/WirelessPhy set RXThresh_ value But I think it just work when creating a node, but What should I do to change transmission power of for example mobilenode(4) after 5 seconds ? Thanks for any help, --Mah
[ns] IEEE 802.15.4 non-beacon star topology
Hello everyone, I am trying to implement a star topology using MAC/PHY 802.15.4 in non-enabled beacon mode. I am using wpan_demo2.tcl and trying to do some changes to the original. To set the beacon mode of I have done the following: $ns_ at 0.0 $node_(0) NodeLabel PAN Coor $ns_ at 0.0 $node_(0) sscs startPANCoord 0 3 3 ;# startPANCoord txBeacon=0 BO=3 SO=3 $ns_ at 0.5 $node_(1) sscs startDevice 0 1 0 ;# startDevice isFFD=1 assoPermit=1 txBeacon=0 BO=3 SO=3 $ns_ at 1.5 $node_(2) sscs startDevice 0 1 0 $ns_ at 2.5 $node_(3) sscs startDevice 0 1 0 $ns_ at 3.5 $node_(4) sscs startDevice 0 1 0 $ns_ at 4.5 $node_(5) sscs startDevice 0 1 0 $ns_ at 5.5 $node_(6) sscs startDevice 0 1 0 In the trace file i get the following (just a part of the file of course): s 0.00256 _0_ MAC --- 0 CM7 8 [0 0 0] r 0.003008033 _3_ MAC --- 0 CM7 8 [0 0 0] r 0.003008033 _1_ MAC --- 0 CM7 8 [0 0 0] r 0.003008033 _4_ MAC --- 0 CM7 8 [0 0 0] r 0.003008033 _6_ MAC --- 0 CM7 8 [0 0 0] r 0.003008033 _2_ MAC --- 0 CM7 8 [0 0 0] r 0.003008033 _5_ MAC --- 0 CM7 8 [0 0 0] s 0.14176 _0_ MAC --- 0 CM7 8 [0 0 0] s 0.28192 _0_ MAC --- 0 CM7 8 [0 0 0] s 0.50064 _1_ MAC --- 0 CM7 8 [0 1 0] r 0.501088033 _2_ MAC --- 0 CM7 8 [0 1 0] r 0.501088033 _0_ MAC --- 0 CM7 8 [0 1 0] r 0.501088033 _6_ MAC --- 0 CM7 8 [0 1 0] s 0.501408033 _0_ MAC --- 0 BCN 11 [0 1 0 0] Meaning that all the nodes are sending and receiving beacon requests (CM7) and node 0 sends beacons (BCN) but no other node recieves them. What am I doing wrong? I don't want any node to be sending beacons or beacon requests! Your help would mean a lot to me cause this is giving me a terrible headache!

[ns] udp protocol
Hi everyone. Can anyone tell me how to send data from one node to another on a udp connection set between two nodes. More specifically i have created five linear nodes. say 0-1-2-3-4. I want to send udp traffic from ( 2 to 0) and and then from (2 to 0 and 2 to 4). Also tell me how to find the throughput in either case?? I would really appreciate the help..
[ns] Problems with loss of Mobile IP packets
I'm using ns2-2.26 the topology is below: two wired nodes, one HA and
three wireless nodes
..--..
..:'' '':..
'''.
|MANET running |
..olsr .'
'':.. +---+ /
''---+--|HA|/
++
\
++---+++-++
|wired | |wired|
|node1|---| node 0 |
+---++ ++---+
We are running NRLOLSR v7.1 and mobile ip in this scenario
the wired nodes and nodes in manet could transfer CBR, and the cbr
and control message of nrlolsr are normal.
The problem is :
when the control messages of Mobile IP is generated and send to
Routing layer, the TTL of the control message is decreased to 1, thus
couldn't be delivered.
the trace file is below:

[ns] [released] Ns-2.33 compiled with Antnet implemented
Dears, Currently many researchers are sending me emails reporting problems in the implementation antnet,so I am put the tarball ns2.33_and_AntNet1.0_compiled.tar.gz ,this package contains the Ns-2.33 compiled with Antnet implemented, the link for download is http://antnet.wordpress.com , the space on the FTP server was provided by Li Amoos. Amoos Lin is Ph.D candidate on Department of Electronic Engineering in National Taiwan University of Science and Technology,Taiwan. To solve some problems in the implementation I am writing a second version of the manual for implementation of antnet in ns-2.33, I report some ‘tricks’. Hope that I have helped.

Re: [ns] understanding trace file
Thank you very much. I was not convinced that the page you pointed me to on the documentation was what i was looking for. so, i kept searching until just now, i stumbled upon a link which said 'x' means end of transmission and is generated just after the last bit of a frame has been transmitted. And it turns out that trace file has these lines only if we use $sim node-config -eotTrace ON I wanted to let you know. Thanks again for the help.

I know threshold -m propagation-model [other-options] distance and Phy/WirelessPhy set RXThresh_ value But I think it just work when creating a node, but What should I do to change transmission power of for example mobilenode(4) after 5 seconds ?

[ns] TCL code for WiFi simulation
Hi! I want to simulate the Wifi scenario and want to analyze the performance of WiFi on increase in number of nodes. The nodes are sending data using VoIP. i want TCL code for this scenario. How will i analyze the trace file using AWK? Thanks!
