2009-08-06 Thread ori and mish bgu

Hi everybody

I wrote a new object class (.h and .cc files) and I want to create an Object
of that class,
and send a pointer to every mac layer in my simulation of that object (get
the pointer in C++), anyone knows how can I do that ?

Thanks

[ns] regarding awk coding

2009-08-06 Thread priyanka ramani


 hi everyone.. 

am new user to ns2... i want to calculate the performance metrics of dsr and 
aodv protocol( end-end delay, throughput, traffic load)... and i dont have idea 
of  calculating these.. could anyone plz send me some awk coding for these and 
tell me how to link this with the respective tcl script and run it? 
my id ( priyanka_1...@yahoo.co.in )... plz anyone kindly send me the coding to

[ns] Call for PhD defense workshop proposals at European Wireless 2010

2009-08-06 Thread Claudio Cicconetti

[we apologize if multiple copies are received]

If you are a PhD student with a thesis in wireless networks and you
already have a draft of your dissertation, you can take the opportunity
to participate to the PhD Defense Workshop co-located with European
Wireless 2010, which will be held in Lucca next April!

You will receive a valuable feedback from the members of a committee
with experienced researchers from both Academia and Industry.
European Wireless attendees are also free to attend and participate to
the discussion with comments and questions.

Up-to-date details are available in the conference website, direct link:
http://www.imtlucca.it/ew2010/technical_program/phd_defense_workshop.php

If you are interested please submit your dissertation proposal to the
Student Papers Co-Chairs , consisting of:

1. A summary (max 5 pages) of the dissertation research including
motivation and challenges, related work, positioning with respect to
the state of the art, initial results. The specific topic addressed,
among those listed in the European Wireless call for paper, should
also be indicated.

2. A short bio (max 1 page), also containing affiliation, PhD
research activities, and expected graduation date.

Only proposals received before December 31, 2009 will be considered.

[ns] Simulate Gigabit Ethernet

2009-08-06 Thread Prince Kaweta

 Hi all,

I want to simulate gigabit ethernet with ns-2. I've arrived to simulate Fast
ethernet (10 Mb/s, 100 Mb/s) but I don't think that MAC 802.3 implement
under ns-2.28 (my ns-2 version) supports gigabit ethernet (Frame bursting,
carrier extension). So if someone had already met the some problem, please
help me with a patch to enhance 802.3 MAC under my ns-2 version or tell me
which modification I should make to implement Frame bursting and carrier
extension in ns-2.28.

Best regards,

[ns] Shadowing model help!

2009-08-06 Thread Ravit Sachasiri

Hi all,

I had been using the TwoRayGround model for a while and tried using the
Shadowing model and discovered something I need help. Well, my packet
delivery success rate had greatly reduce from 100% to 30% when i switch from
Freespace or Tworayground for path loss exponent =2 (same as free space) and
shadowing deviation = 1. I checked that if my shadowing deviation is 0, the
model give same result as free space model.

I dug in further and found out a criteria where packets were being dropped.
It is in the wpan/p802_15_4mac. cc.

Line no 1031:

if ((wph->rxTotPower-p->txinfo_.RxPr) > 0.0)
if (p->txinfo_.RxPr/(wph->rxTotPower-p->txinfo_.RxPr) <
p->txinfo_.CPThresh)
{
drop(p,"LQI");
return;
}

I understand here that the power receive is checked to see if it is more
thatn CPthresh times the power of interfering packets and if yes, the
packets are dropped.

In my scenerio, there is only two nodes with node 0 transmitting to node 1
only. When I use the TwoRayGround propagation, the value of power of
interfering packets are always 0 and hence no packets are ever dropped for
this reason but in Shadowing model, there is always some interfering power
with some packets getting dropped due to the fact that the power due to
interference high enough for the frame to be considered corrupted, and for
shadowing deviation =1, it is 70% of all transmitted packet. The condition
for both transmission is same and I am sure there is no interfering packets.

Another interesting thing that I noted was that the power received of the
packet with the TwoRayGround model is always the same and in the order of
10^(-12) and the interfering power is 0 while for shadowing model, the
received power of that packet is in the variation from 10^(-9) to 10^(-11)
with the interfering power also in the same order of magnitude.

Could someone please help explain me the shadowing model and also maybe why
there is interference when there is supposed to be none? Also, any other
explanation to help explain what values are the usual standards for
shadowing model will alsobe appreciated.

Thank you.

Sincerely,
Ravit Sachasiri
