4. Project overview
Adaptive computing: solutions that adapt to their environment
Linked to ubicomp / pervasive computing / proactive computing vision
Our projects relate to
Context-awareness (CONTEXT, Space4U, MobiLife)
Ad hoc networking (NAPS)
They are
Fundamental research (NAPS, CONTEXT)
Systems-oriented (CONTEXT, Space4U, MobiLife)

5. PROACT coordination
Academy of Finland research programme (also TEKES, French Ministry of Research), Jan 2002 – May 2006
Programme Manager Heikki Mannila and Coordinator Greger Lindén
14 projects with 41 partners
Follow-up, assistance, promoting collaboration

6. NAPS (1) Part of PROACT programme, Jan 2003 - Dec 2005
With HUT/Theoretical Computer Science (Prof. Pekka Orponen) and Networking Lab(Prof. Jorma Virtamo)
People: Patrik Floréen, Jukka Kohonen
The algoritmics subproject works on fundamental topology control and routing problems in energy-constrained ad hoc networks (also sensor networks)
Theoretically oriented work: problem complexity, optimization, upper bounds, not full protocols

7. NAPS (2) Results Webpage: www.cs.helsinki.fi/hiit_bru/projects/naps
Complexity and heuristics for multicasting lifetime maximization under energy constraints (publication in DIALM-POMC workshop , MobiCom 2003)
Balanced data gathering in energy-constrained sensor networks (publication to appear in Algosensors workshop, ICALP 2004)
Webpage:

8. CONTEXT (1) Part of PROACT programme, Nov 2002 - Dec 2005
Jointly with ARU (UERG)
People: Hannu Toivonen, Kari Laasonen, Renaud Petit, Mika Raento
Analysis of information about user’s context and its use
Also prototype implementation

9. CONTEXT (2) Results Webpage: www.cs.helsinki.fi/group/context
Learning and predicting personally important locations in cellular networks and using them in presence service (automatic annotation of photographs), implemented on Symbian mobile phones (publication in Pervasive 2004)
Webpage:

10. Space4U (1)
Nokia subcontracting, ITEA project (EUREKA), July June 2004, continuation under negotiation July June 2005
Also involved is HUT/Information Processing Science (Prof. Juha Tuominen)
People: Patrik Floréen, Otso Virtanen

11. Space4U (2)
Context-aware selection of software components in mobile phones
Building on the ROBOCOP component framework from the preceding project
Results
Context-aware configuration framework using a blackboard-based approach (publication to appear in ECOOP2004)
Overall Space4U webpage:

12. Other ongoing research
Own BRU funding
People: Patrik Floréen, Greger Lindén, Yevgeniya Kulikova, Petteri Nurmi
Topics
Deriving the computational context on a desktop
Applying reinforcement learning to context
Only initial phase of work on which to build in the future

13. MobiLife (1)
Nokia-coordinated EU IST Integrated Project belonging to the WWI Initiative
Possibly starting in Sept 2004, 28 months; idea is to continue with a follow-up IP
Both HIIT/BRU and HIIT/ARU are partners, in total 22 partners
123 person-years of work, a budget of 17,3 million euro with Commission contribution of 9,7 million euro

14. MobiLife (2)
The work includes an inventory of the requirements for future Wireless World services and applications through scenario work and user experiments, development of enabling components (i.e., personalisation, privacy and trust, and context-awareness) for building such services and applications, and development of representative example applications and services including prototype implementations and user experiments with these prototypes

15. Some future plans Topics More software development work
In Space4U, there is a component approach; we would like to develop generic context reasoning components
Dependency on roles/identity is interesting; we would like to work on detecting and using roles/identity
More software development work
Recruitment of programmers; also postdocs
TEKES projects

16. 2. Position within HIIT How it fits in the overall HIIT picture
How it fits within BRU

17. How it fits in the overall HIIT picture
Many other areas of HIIT study adaptive computing / context-awareness / personalisation
Fuego
CoSCo
Aiming at synergy: the whole idea of bringing different groups together into one research institute
But we do not do the same and do not have the same background

18. How it fits within BRU
BRU research areas are data analysis, adaptive computing and neuroinformatics
Within BRU, linked to the data analysis work (e.g. CONTEXT)
Builds also on earlier expertise in algorithmics and language technology
Interacts with machine learning and language technology at the Department of Computer Science

19. 3. Discussion: Way forward for context-awareness
Lack of agreed context representation and architecture for context-aware applications hinders the development and makes application development expensive (stand-alone solutions)  middleware needed to separate sensors and applications
Examples of different architectures proposed (Human Computer Interaction, Vol. 16, 2001)
Context Toolkit (Salber, Dey, Abowd)
Service infrastructure (Hong, Landay)
Blackboard architecture (Winograd)

20. ITEA Technology Roadmap for Software-Intensive Systems, 2nd ed
ITEA Technology Roadmap for Software-Intensive Systems, 2nd ed., May 2004
Four technology clusters (with some key citations)
Content: “content without context or meta-data is of little or no use”
Infrastructures & Basic Services: “security will become pervasive”
Human-System Interaction: “hide underlying complexities from users and provide the best possible user experience, so that the user feels in control”; “UIs will need to be able to learn user preferences”
Engineering: “software engineering … that support the efficient implementation of embedded systems”; “appropriate business models”
