ITU Kaleidoscope 2016 ICTs for a Sustainable World ASSESSING INTERNET PERFORMANCE OVER MOBILE NETWORKS: FROM THEORY TO PRACTICE Eneko Atxutegi University of the Basque Country eneko.atxutegi@ehu.eus Bangkok, Thailand 14-16 November 2016
Experimentation stair (I) Experimentation level Simulated environment Emulated testbed Controlled deployment Real-world deployment Pros -Repeatability -Cheapest option -Parameters gathering -Real UEs -Easy LTE configuration -Radio info. collection -Real movement -Ad-hoc patterns -Air transmission -Real speeds -Real patterns -Ability to study realism Cons -Synthetic fadings -Faked UEs -Hard modeling -Statistics required -No real movement -Speed/space limitation -Limited parameters study -Data quota Reduced deployments are hardly capable of reproducing the coverage that is present in real base stations, causing an unrealistic good quality at any position. Found that under exactly same conditions, different UEs report a way different CQI to the enodeb. Bangkok, Thailand, 14-16 November 2016 ITU Kaleidoscope 2016 - ICTs for a Sustainable World
Experimentation stair (II) Micro-effects could not be presented as equal among the different deployments (example of Hybrid Slow-Start s deficiency on mobile networks under high delay variability). However, the macroscopic view of some behavior could be found and double-checked along the different steps (example of some CCAs features).

ITU Kaleidoscope 2016 ICTs for a Sustainable World Systematic Analysis of Geolocation and Spectrum Sensing as Access Methods to TV White Space Antoine Bagula University of the Western Cape abagula@uwc.ac.za Bangkok, Thailand 14-16 November 2016
Developed world vs. developing world Use of TV radio frequency spectrum is different. Intensively used in the developed world. Preferred method of TVWS in the developed world: Geo-location database. Preferred method of TVWS in the developing world:??? Visit my poster to learn more. Bangkok, Thailand, 14-16 November 2016 ITU Kaleidoscope 2016 - ICTs for a Sustainable World
ITU Kaleidoscope 2016 ICTs for a Sustainable World Task-based process modeling for policy making in smart cities Leonidas Anthopoulos TEI of Thessaly, Greece lanthopo@teilar.gr Bangkok, Thailand 14-16 November 2016
Grounding the problem RQ1: do existing smart city standards provide guidelines for city s energy efficiency policy making? RQ2: how can smart city energy efficiency policy making be modeled and standardized? Approach: Standardize the policy making process for city s energy efficiency Map the policy making process: Task-Based Modeling (TBM) method Experimenting in cities under the project InSmart (Integrative Smart City Planning) Bangkok, Thailand, 14-16 November 2016 ITU Kaleidoscope 2016 - ICTs for a Sustainable World
The Standardized Process Reference framework Energy demand sources Energy supply sources Scenarios definition (alternative policies) Scenarios execution (calculation with model) Scenarios outcomes: policies estimated performance Multi-criteria Decision Making Process Bangkok, Thailand, 14-16 November 2016 ITU Kaleidoscope 2016 - ICTs for a Sustainable World Criteria: 1. Implementation Cost 2. Implementation Cost Efficiency 3. Energy savings 4. Operation and Maintenance Cost 5. Revenue Production 6. Ease of Implementation 7. City s Quality of Life Improvement 8. City s Economic Development Improvement 9. Social Acceptance

ITU Kaleidoscope 2016 ICTs for a Sustainable World Cloud-based Patient Prioritization as Service in Public Health care Antoine Bagula University of the Western Cape abagula@uwc.ac.za Bangkok, Thailand 14-16 November 2016
Cloud-based Patient Prioritization As Service in Public Health care Technology can help improve public health in both developed and developing countries. It can help developing countries to leapfrog from poorly equipped to medically prepared nations. It can also help minimize the impact of some of the most vicious epidemic attacks such as Ebola. Some of these technologies include: IoT/Sensor AI/Machine Learning Cloud computing Communication Solar/Wind We have been testing these five technologies for Patient prioritization in the developing countries.
