2. doc.: IEEE 802.11-13/1000r1 Submission Summary 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 Aug 2013 Slide 2Simone Merlin (Qualcomm)

3. doc.: IEEE 802.11-13/1000r1 Submission Definition of “Simulation Scenario” A simulation scenario is defined by –Topology: AP/STAs positions, obstructions, layout, propagation model –Traffic model 1.STA - AP traffic 2.P2P traffic (tethering, Soft-APs, TDLS) 3.‘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 –An interfering scenario (its performance may not be 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 Aug 2013 Slide 3 Simone Merlin (Qualcomm)

4. doc.: IEEE 802.11-13/1000r1 Submission 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 Aug 2013 Slide 4Simone Merlin (Qualcomm)

5. doc.: IEEE 802.11-13/1000r1 Submission 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 Aug 2013 Slide 5Simone Merlin (Qualcomm)

6. doc.: IEEE 802.11-13/1000r1 Submission 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 Aug 2013 Slide 6 Simone Merlin (Qualcomm)
