Fuego Future Mobile Computing Kimmo Raatikainen Helsinki Institute for Information Technology

Fuego Mission ”Any technology distinguishable from magic is insufficiently advanced,” Gregory Benford To address the research challenges arising in mobile computing systems and applications of tomorrow. Mobile computing will fulfill the vision of ubiquitous - invisible - computing providing access and services anytime, anywhere, and anyhow.

Key Challenges The key challenges are related to –context-awareness, –adaptability, –reconfigurability, –understanding user needs, and –personalization.

Current research topics Fuego Core –Middleware for Mobile Wireless Internet – Sarcous –Software Architectures for Configurable Ubiquitous Systems – PDIS –Personal Distributed Information Storage – CONTEXT –Context Recognition by User Situation Data Analysis

Fuego Core Kimmo Raatikainen Pekka Nikander Sasu Tarkoma

Fuego Core in Nutshell to specify the set of fundamental enabling middleware services for mobile applications on future mobile environments to implement two research prototypes and participate in relevant standardizing forums (W3C, IETF, OMG, OMA) Work areas: Adaptive Applications, Mobile Distributed Information Base, Reconfigurable Services, and Mobility, Multi-homing, and Cryptographic Host Identification Host Identity Protocol XML Protocol Distributed Events Synchronization Presence

Sarcous Tomi Männistö

Problem area Software product families / lines =managing the large variety of software products, e.g., due to high customer-specific customisation, diverse markets or hardware (especially in embedded systems) A software product family consists of an architecture and assets that are used for producing individuals of the family Individuals of a product family may be software or services

Research Questions What are the real needs in applying configurable SPF in the industry? How should the architectures and components of real SPF and their evolution be modeled? What is the conceptual basis for configuring web services implemented by means of software? What kind of intelligent support can be offered for dynamic configuration of software, e.g., of a mobile terminal? How can configuration knowledge be managed in a distributed environment?

Results thus far Survey on software product families –Five companies surveyed, analysed and results reported to companies Modelling –Conceptual foundation and synthesis of relevant existing modelling concepts –Configuration according to Koala language of Philips –Evolution Tools and prototyping –Research environment for investigating configurable software –Configuring a Linux Familiar distribution for Compaq iPAQs –Using WeCoTin for configuring Linux familiar –(Re)configuration with multiple Linux distribution versions

PDIS Ken Rimey

PDIS in Nutshell Synchronization-based peer-to-peer infrastructure for storage of structured XML data. PIM data. Metadata for digital media. Calendar data is test case Nokia, HP, Innofactor, Creanor Movial, Tekes Team at HIIT: Ken Rimey (responsible lead), Kenneth Oksanen, Torsten Rüger

PDIS (continued) Update-anywhere replication, eventual consistency. Beyond SyncML: –Synchronize any subset of a database efficiently. –Don’t fetch what has already arrived from any other device. –Merge changes in an application-independent way. Wireless use-cases for synchronization: –Everywhere all the time, low bandwidth, high latency (GPRS) –Work session at hot-spot (WLAN) –Brief session for sync or explicit transfer (Bluetooth)
