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. 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.
