Subject: Ad hoc group on
evaluation - Soliciting contributions to developing Usage Models/Scenarios
Dear all,
To follow-up on our telecon discussion this morning, the evaluation ad hoc
group would like to solicit volunteers to develop
a set of usage case models & scenarios to be included in the evaluation
guidelines document.
Although the consensus was that no
performance analyses, modeling, and simulation results will be required for the
proposal
down-selection process, there is some value to develop template scenarios in
order to allow for simulation modeling / prototype implementation at a
later stage - after harmonization has occurred.
[Gupta, Vivek G]
The evaluation guidelines document should basically help
with evaluations and down selection.
If the above information is NOT going to help with
evaluation and down selection, then it should NOT be included in evaluation
guideline document.
Usage scenarios should include enough details to allow for an experimenter to
collect performance measures using either simulation, mathematical modeling, or
prototype implementation, to replicate and compare results.
Typically usage scenarios consist of::
1) Description of the application or traffic characterization: e.g. voice,
video, file transfer, email, etc.
2) Network topology: number, type, location, coverage of access networks (802.11,
802.16, cellular, etc.), location of mobile node or multi-interface terminal
(distance from access network).
3) Mobility or handover model : description of a path from one
access network to the other.
4) Meta usage models eg. residential, office,
airport, train., that would associate a set of parameters to the above
three elements.
5) Performance measures
6) whatever else you think may be needed
If you're interested in contributing to this effort please send your thoughts
to the reflector.
Reijo Salminen has graciously agreed to consolidate the ideas and input
received and fold that into a section on
usage scenarios in the evaluation guidelines document.
Best Regards,
nada
