  • 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.

  • 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

  • f some CCAs’ features).

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: ???

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

slide-12
SLIDE 12

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)

The Standardized Process

  • Reference framework
  • Energy demand sources
  • Energy supply sources
  • Scenarios definition

(alternative policies)

  • Scenarios execution

(calculation with model)

Bangkok, Thailand, 14-16 November 2016 ITU Kaleidoscope 2016 - ICTs for a Sustainable World

  • Scenarios’
  • utcomes:

policies’ estimated performance

  • 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
  • Multi-criteria

  • 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.
