  • My name is 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 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
  • 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)
