HIIT

• Helsinki Institute for Information Technology
  HIIT is a joint research institute of University
  of Helsinki and Helsinki University of Technology
  TKK founded in 1999
• It consists since 2002 of the Basic Research Unit
  (BRU) and the Advanced Research Unit (ARU)
• According to the approved strategy of HIIT, the
  units will be merged by the end of 2008
• The research is now unified across BRU and ARU
  into four programmes
• Operations in Kumpula, Tapiola and Otaniemi

Research programmes

• Algorithmic Data Analysis (ADA) Data analysis
  methods for other sciences and for industry
  through both basic research in CS and applied
  work on problems arising from applications
• Future Internet (FI) Internet infrastructure for
  efficient, secure and trusted always-on
  connectivity and services
• Network Society (NS) Human-centric
  multidisciplinary anticipation and development of
  ubiquitous information and communication
  technology
• Probabilistic Adaptive Systems (PAS)
  Sophisticated probabilistic models and their
  applications for solving problems appearing in
  complex real-world stochastic systems

Ubiquitous computing at HIIT

• Ubicomp is studied in many research groups of
  HIIT
• Middleware, security, trust in the Future
  Internet programme
• Interaction and media research in the Network
  Society programme
• Context-awareness and sensor networks in our
  research group Adaptive Computing
• We have collaboration throughout HIIT, but in
  particular with UIx in NS and CoSCo in PAS

6
Adaptive Computing group

• Our group conducts research on modelling and
  optimisation in resource-constrained distributed
  environments
• Our work concentrates on
• data analysis, probabilistic modelling and
  component-based development for mobile
  context-aware systems
• ad hoc and sensor networks
• Collaboration with industry important
