  • My name is <name> I work at the Application Architecture Lab I am also a doctoral student with prof Maguire whoi heads the CCSlab at KTH My talk is about <title> and will both outline our research regarding smart adaptive mobile applications and in this talk my colleague Tom Rindborg and I will also present a demonstration which we developed.
  • This is to exemplify what we mean by a heterogeneous wireless infrastructure
  • The key ideas for smart, adaptive applications are that
  • What are the challenges?
  • Clearly, we can be smart about our communication...

      • Adapt to User Context
      • Mobile Groups
  • 12. Summary
    • Applications can be smart and adapt
      • To the User’s context and thus exhibit more interesting or relevant behavior
      • To the communication conditions, by learning and inferring from events, hence how to behave more optimally
    • Applications, Services will and are choosing networks (or combinations of these)
      • WLAN/2.5G/3G
      • Think about making more optimal use of available infrastructure, rather than being only inventive about putting complexity back in (e.g., 3GPP IP MM Subsystem)
