  • 1. Tina Balke, University of Bayreuth / University of Bath NORMATIVE MODELS FOR EVIDENCE-BASED PROCESS ANALYSIS OF WIRELESS MOBILE GRIDS
  • 2. Tina Balke, University of Bayreuth / University of Bath WIRELESS MOBILE GRIDS: POTENTIAL STARS, CASH COWS, QUESTION MARKS OR DOGS AND HOW TO FIND OUT?
  • 3. Financial Challenges for the Mobile Phone Sector Intensifiedcompetition due to market penetration of 132% (EU) ARPU: 15/month (Germany) Negative profit margin of -7% is expected by 2012 (for some companies, negative EBITDA expected) (EU)
  • 4. Infrastructure Challenges for the Mobile Phone Sector Application demand for digital content is rising Infrastructure network capacity is limited Smartphone battery life cycle poses a big problem, and is considered especially important by customers Smartphone compute and ad-hoc network facilities are under-utilized
  • 5. Wireless Mobile Grids A Solution!?
  • 6. The Public Good Problem in Wireless Mobile Grids
  • 7. Life Cycle Costs Source: BCG
  • 8. Essential Question: How to can we find out if wireless mobile grids can actually work and are worth investing in?
  • 9. Norm. Models for Evidence- Based Process Analysis Technical Foundations (Energy & Transmission Normative Model Model) Normative Multi- Agent-System Simulation Financial Model User Model
  • 10. Early Results Power Levels and Data Rate For WLAN Broadcast - 1000 byte state power value [W] data rate [Mbps] sending 1,629 5,623 receiving @ 3m 1,375 5,379 idle @ 3m 0,952 - Power Levels and Data Rate For Cellular - 100 byte state power value [W] data rate [Mbps] receiving 1,314 0,193 idle 0,661 - Source: Gian Paolo Perrucci, Aalborg University
  • 11. Early Results II Analytical normative model ignoring strategic user behavior potential for wireless mobile grid solution Normative MAS model without enforcement with strategic user behavior significantly worse energy consumption
  • 12. Early Results III Financial results: On average 85% EBITDA increase for idealized Wireless Mobile Grid model in Germany
  • 13. Future Research More realistic models User interaction and the overall system results Financial model Empirical study on Wireless Mobile Grid user preferences Multi-stakeholder analysis Test implementation in Aalborg Location-based services
