[ns] WFQ v1.2.5
Hi A new version of WFQ for the NS-2 simulator is available. http://www.cc.jyu.fi/~sayenko/src/wfq-1.2.5.tar.gz The new version solves several small compilation problems that you can experience if you use the latest gcc compiler versions. This version has been tested with the following NS-2 versions: v2.27, v.2.28, v2.29 and v2.30.

[ns] Fwd: Please help
Hello,
I am trying to create a new class called as myNode, that has *
Node/MobileNode* as its superclass.
I want to create a hierarchy of nodes as Grand Parent, Parent and Child.
The following error is being triggered. Please tell me if I have to
initialize anything to avoid this error.
*"Assertion failed: initialized(), file common/mobilenode.cc, line 408*
*This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information."*
The code for creating a class is as given below:
Class myNode -superclass Node/MobileNode
myNode instproc init {args} {
# Parent class constructor
eval $self next $args
$self instvar role_
set role_ 0
}
myNode instproc define_role { arg } {
set role_ $arg
# 1 is Grand parent
# 2 is Parent
# 3 is Child
}

Thanks,
Megha
[ns] LL implementation in ns-2 RFC conformant?
hi, I was wondering whether LL (link layer) implemented in current version includes timer mechanism. I plan to have two node connected to LAN and have them send data with acknowledgment mode of LL. I could not find a hint in the latest ns-manual whether a retransmission request is abandoned once there is not reply in some predefined time? Example: host1 <==> host2 (sender)ethernet (receiver) Once host2 detects a missing frame, it requests host1 to resend the concerning frame. However it would not wait forever for retransmission of this frame. After a timer is expired, this frame is marked as missing. This is how standard (RFC) says. I do not know whether something like is enabled in current version of ns2? Your thoughts are much appreciated. Regards, -- Luqman

Maybe you can use "create-trace", "drop-trace", "trace-queue" etc.. instead of "trace-all". $ns_ create-trace Here create-trace allows to define src and dst nodes that are to be traces. With type and optional:op you can further reduce the size of trace. I didn't find quickly how to set value though. Maybe someone on this list can help. Furthermore, "NS simulator for beginners" describes how to reduce size of trace files with gawk, perl, grep etc. under unix-based operating systems. Good luck. Regards, -- Luqman

Re: [ns] NS-2 VALIDATION PROBLEMS AFTER EXTENDED WITH MANNASIM
Hi, I think something went wrong when you reinstalled ns-2 over the patched version. I use mannasim and my validation still runs correct (as far as I remember). Best, -Matt Am Mittwoch, 22.

Re: [ns] warning: no class variable God::path_analysis_
Hi, To solve this problem, simply add the following line in "tcl/lib/ns-default.tcl" file (with god parameters): god set path_analysis_ 0 Best wishes, samer --- Matthias Budde matthi.budde at web.de wrote: Wed Oct 4 09:53:41 PDT 2006 Hi, After applying the GPSR patch to ns 2.29.3, I get the following warning message when running simple-wireless.tcl from Marc Greis' Tutorial: warning: no class variable God::path_analysis_ What does this mean?

[ns] doubt in hcca patch to ns2
Hello all, I am working on a project on 802.11E schedulers. I am trying to implement WFQ scheduler with some minor modifications, using the ns2HCCA patch for NS-2.27. However, I am facing the following problems: 1. Where (in the code) does a CAP start mechanism take place. There is a startCAP(void) function in mac-802_11e.cc file, but it is called twice. Once, when we specify start-hcca in the TCL script and second time when we pass the TSPEC parameters in the TCL script. Is this function called only when the QAP starts a CAP? 2. How does the patch ensure that the TXOP list that is created is being followed fully. Consider the offline TXOP list that is created. Suppose it contains the TXOP times for the stations 1,2,5,6. How does the patch ensure that first only station 1 will access the channel, and then stations 2, 5, 6 ... and so on. How is this being ensured? 3. How do the stations get access to the channel i.e. how does the channel access switch mechanism take place. E.g. Suppose at time t station 1 is accessing the channel. After time t+t1 , i want station 2 to access the channel. How can i do that? I would be really grateful if anyone could explain me the working of the patch w.r.t the questions mentioned above. Also, any suggestion as to how to go about implementing the WFQ scheduler would be welcome. Thanks in advance, with regards, Sandeep.
