Summary Aug 2013 Simulation Scenarios definition Proposed definition Proposed template description format Discussion on the set of scenarios Summary of IEEE discussion so far Proposal for identifying a minimum set of simulation scenarios Simone Merlin (Qualcomm)

Definition of “Simulation Scenario” Aug 2013 Definition of “Simulation Scenario” A simulation scenario is defined by Topology: AP/STAs positions, P2P STAs pair positions, obstructions , layout, propagation model Traffic model STA - AP traffic P2P traffic (tethering, Soft-APs, TDLS) ‘Idle’ devices (generating management traffic such as probes/beacons) List of PHY, MAC, Management parameters We may want to fix the value of some parameters to limit the degrees of freedom, and for calibration Optionally, some STAs may use legacy (11n/ac) operation parameters, if required to prove effectiveness of selected HEW solutions An interfering scenario (its performance optionally tracked) Not managed or managed by a different entity than the one of the main scenario Defined by its own topology, traffic model and parameters The group should adopt a common way to describe a scenario See a tentative template in document 11-13/1001r0 Simone Merlin (Qualcomm)

Definition of “Simulation Scenario” Aug 2013 Definition of “Simulation Scenario” The purpose of a simulation scenario is not to exactly simulate a usage model, but rather to capture the key characteristics of that usage model, relevant for testing the effectiveness of new HEW solutions There may be multiple usage models mapped to a same simulation scenario We should define a preferably reduced number of simulation scenarios that cover most of the usage models It is useful to limit the number of simulation scenarios to a minimum set that represents the most important challenges for HEW Avoids to have up to 18 scenarios (one per usage model) Helps to better identify the goals for HEW Facilitates comparison Simone Merlin (Qualcomm)

Current Status and Goals Aug 2013 Current Status and Goals Several presentations at previous meetings proposed simulation scenarios see References, appendix and next slides Multiple of the proposed scenarios targeted a same usage model, but had different topology/setup In the next slides we try to Classify the proposed simulation scenarios, identify the commonalities and come up with a minimum representative set Define the next steps Simone Merlin (Qualcomm)

Current Status – Classification Aug 2013 Current Status – Classification Presentation [1-13] classified the simulation scenarios mainly based on Topology: Density of STA, Density of APs Management Infrastructure APs belonging to same management domain (e.g. same operator) P2P traffic included in the scenario may not be managed Interference from overlapping networks is not managed Or, each AP belong to different management domain (e.g. in a apartment building) Propagation: Indoor only, Outdoor only, Mixed Homogeneity All APs with similar coverage (flat) APs with significantly different coverage and overlapped (hierarchical) Traffic models were not well specified per each scenario Tentatively 3 representative traffic profiles are named as ‘Home’, ‘Enterprise’, ‘Mobile’ an associated to the scenarios based on reasonable guesses The goal is just to point our which scenarios may use a similar traffic model, not to define the traffic model In the next slides we classify the scenarios based on above criteria and tag them with a new name, giving a same name to scenarios that are similar Simone Merlin (Qualcomm)

Proposed Unified Set of Scenarios Aug 2013 Proposed Unified Set of Scenarios The identified scenarios in slide 9 cover most of the challenging usage models that will put HEW solutions to a test Would the group agree to adopt these scenarios as a baseline set? i.e. these scenarios to be used for proving effectiveness of HEW solutions If yes, we need to define each of them in details Call for submissions following the template in 11-13/1001r0 Some usage models seem not covered by the baseline scenarios Do we need more scenarios? Simone Merlin (Qualcomm)

Conclusion Aug 2013 Defined what a Simulation Scenario is Identified a baseline set of simulation scenarios from earlier IEEE presentations The scenarios seem representative of most of the key aspects to be investigated in HEW and cover most of the usage models Do we agree to use these scenarios as a reference set? i.e. these scenarios are used for proving effectiveness of HEW solutions Call for submissions for refining scenarios description Following the proposed template in 11-13/1001r0 Some usage models are still not mapped to a simulation scenario Do we need more scenarios?
