Re: [ns] Newbie questions on wpan demo

[Bruce Who]

Finally I add ErrorModel to wpan_demo2.tcl, and but the result I get
is quite different from the that of the paper "A Comprehensive
Performance Study of IEEE 802.15.4" which is written by the author of
wpan module.

Here is my result:

pps is 15.1
throughput is 1.6 KBps
packet delivery ratio is 98.7 %
pps is 4.8
throughput is 0.6 KBps
packet delivery ratio is 98.0 %
pps is 2.6
throughput is 0.4 KBps
packet delivery ratio is 97.0 %
pps is 1.4
throughput is 0.3 KBps
packet delivery ratio is 96.7 %

The paper says that as pps goes bigger, the packet delivery ratio
should go down.

I guess it's quite possible that I have made some mistakes, but I
cannot find out myself.
The attachments are my scripts:

run: just type ./run to run the simulation and you'll see the result
wpan_demo2.tcl: I made some changes to the original wpan_demo2.tcl
calc_wpan2.py: it's used by ./run to caculate pps and packet delivery ratio

[ns] 802.11 MAC code in NS-2

[Saurabh Sinha]

I went through the article "http://www-ece.rice.edu/~jpr/ns/docs/802_11.html";
which is awesome, but i have doubts in my mind like.

Q1) Like which c++ fuction exactly calls the recv() function?

Q2) Now, when you say the control resumes after the timer expires, what do
you mean by that?

Q3) Also, when is this code (say Mac802_11) called, like whenever a packet
or station (node) wise?


I'm trying to implement the EDCF (802.11e) and for that these will of great
help of mine.

[ns] DSDV in inifite loop with certain physical layer threshold - help

[Sasan Sahraei]

Hi All,

In DSDV, when using

Phy/WirelessPhy set RXThresh_ 3.652e-10

I always get the rtable metrics = 250 and DSDV_Agent::helper_callback
never gets called to update the table (through makeUpdate)

so this leads forwardPacket to get into an infinite loop

but when using

Phy/WirelessPhy set RXThresh_ 1.47635e-07

there is no such problem, but inturn, it result in so many packets to be
dropped.

I can imagine why the second one drops so many packets, but I can't
understand why DSDV gets into infinite loop when using

Phy/WirelessPhy set RXThresh_ 3.652e-10

any opinions will be appreciated.

Thanks,
Sasan

This is a problem with the latest gcc version. To fix it, you can modify 
the files by moving the Xmit*Callback functions to the beginning of the 
file. Otherwise you could get updated versions of the files from the CVS 
- I already fixed this 3 weeks ago.

You can also downgrade your gcc to a 3.3 version.

[ns] more then one CBR connection in a large network

[Semih DOKURER]

Hi;

 

I have created 20 CBR connections over UDP of 50 wireless nodes using for
loop in TCL. The code is compiled but when the NAM run it, I saw that
connections doesn't work as I programmed. Its trace file proves it. For
example, one of the connections, even tough I took out the forwarded
packets, number of received packets at receiving node is more then sent
packets at sending node. My TCL code is below. I think there is a mistake.
I will be appreciated if any body can explain the mistake or say the
necessary code to create 20 CBR connections. 

Thnx

Re: [ns] energy model in ns

[Qasim Raza Iqbal]

Hi Amrutha

At the moment the sleep cycle is only implemented in SMAC protocol used in
wireless sensor networks. The 802.11 or any other protocol do not have
sleep cycle (anyone correct me if I am wrong).
also the energy is decreased for units/second. e.g if your transmit energy
is set to 5, then for total transmission for a second/ 5 units will be
deducted. these deduction can contribute from MAC/RTS/CTS or any other
message being transmitted.
I have not used TCP, so I could not answer the seconf question
