Experimentation stair (I) Experimentation Pros Cons level -Repeatability -Synthetic fadings Simulated -Cheapest option -Faked UEs environment -Parameters gathering -Hard modeling -Real UEs -Statistics required Emulated testbed -Easy LTE configuration -No real movement -Radio info. collection -Real movement Controlled -Speed/space -Ad-hoc patterns deployment limitation -Air transmission -Real speeds -Limited Real-world -Real patterns parameters study deployment -Ability to study realism -Data quota  Reduced deployments are  Found that under exactly hardly capable of same conditions, different reproducing the coverage UEs report a way different that is present in real base CQI to the eNodeB. stations, causing an unrealistic good quality at any position.

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 Geo- location 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.

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 • • Scenarios’ Energy demand sources • outcomes: Energy supply sources • policies’ Scenarios definition • estimated (alternative policies) performance Scenarios execution • (calculation with model) • Criteria: Multi-criteria • 1. Implementation Cost 2. Implementation Cost Efficiency Decision Making 3. Energy savings 4. Operation and Maintenance Cost Process 5. Revenue Production 6. Ease of Implementation 7. City’s Quality of Life Improvement 8. City’s Economic Development Improvement Bangkok, Thailand, 14-16 November 2016 9. Social Acceptance ITU Kaleidoscope 2016 - ICTs for a Sustainable World

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.
