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
Hi,
I got it. Page 127 of ns-doc.pdf tells us how to do it. But it's
really hard to find it. I thought it is covered in "Chapter 16 Mobile
Networking in ns" or "Chapter 6 Links: Simple Links"
Another question,
How long does it take to transmit a packet? I found this snippet in
ns/tcl/ex/wpan:
Hi Bruce,
Read chapeter 13 in ns-manual.. I think you are looking for Error Model
instead of Loss Model.
The commands you are using are for wired networks only, if I am not
mistaken.

Hi Bruce,
If you enable AGT and RTR tracing (in node-config command in the tcl
file), you will see that when a tcp packet is sent out of the RTR layer,
its size is larger than its size when sent by the AGT layer. This
reflects the fact that the RTR layer adds some headers that contribute
to the p

2) assoPermit means whether the node should permit other nodes to
associate with it so that it becomes their coordinator. Look at the
802.15.4-2003 standard for details.
5) This is not how LossModel is used. Consult ns-manual for the correct
usage. It still applies for wpan.

Hi, Stan:
I read the slides distributed with the wpan modules, but I can only
find some descriptions for the commands and cannot find answers to my
questions. I'll look for papers and may get the answer to the question no.2,
but I don't think I can find any clues to the others. I read
