RE: stds-802-16-mobile: Channel Model
Dear Ron Murias
thank you, but in the attachment you sent me "low level"
channel models are described. I've already red this document and some its
references.
Could you tell me how are you "currently using the same model for
the fixed application" to estimate the performance of the high
levels of network architecture (Mobility Agent, ATM, IP ... TCP,
application protocols, ...)?
Best regards.

Hi
Cosimo,
We're currently using, as a
starting point, the same model we created for the fixed
application. I've attached that model. From there, you should
be able to apply changes applicable to your application. I'm not
sure this is what you're after, but it's a start.

- Dear members,
- I'm an undergraduate student of the University of Lecce (Italy): I'm
doing a research about the TCP performance in the wireless
environment.
- I'm studying a network composed by more wireless networks (little
range networks like 802.11e, and big range networks like 802.16e) that
are connected together.
- In this moment I'm trying a channel model for each wireless section
of my scenario of study. My goal is to formulate a Markovian channel
model (or similar) to simulate the activity of 802.16e in urban
environment (an example of a simple channel model-based on Gilbert-Elliot
model is at http://cwc.ucsd.edu/~rao/pubs/1995_icupc_p211-5.pdf); the BS
is fixed but the SSs are mobile (vehicular velocity, 20-80 Km/h).
- I've red some document about 802.16e project
(http://wirelessman.org/tge/index.html)
and about 802.20 project
(http://grouper.ieee.org/groups/802/20/Contributions.html)
in which I've found some information for my research (Vehicular models),
but I'm trying an "high level" channel model (e.g. the
Gilbert-Elliot model) that respects the features of the studied "low
level" channel models.
- Could you tell me where I may find some information (papers,
experimental data, etc) about my research?
- Could you tell me other researchers ("channel modelers") of
802.16e project that help me or that work (or worked) for this project to
estimate the 802.16e performance?
- Thanks in advance.
