Connectivity and partition detection

Objectives

 Mobile Ad-hoc Networks (MANETs) ⇒ Partitionable systems  Partitioning ⇒ Degradation of service, but not necessarily unavailability

Approach

 Group Communication System = Membership + Multicast

Proposition

 Sequence of Abortable Consensus for group membership

Current interests

 Distribution of context information, mobile commerce, pervasive games

Consistency and Replication

Objectives

 Maintain replicated copies consistency for ubiquitous computing  Consider discrete and continuous applications

Approach

 Consistency management as an extra-functional middleware service

Proposition

 Synchronisation Medium  RFID-based Distributed Shared Memory

Current interests

 Mobile multiplayer games. Plug: Secrets of the Museum RFID/NFC tags hold the system memory Players constitute the network

Context Management

Objectives

 Consistent view of the execution context  Identification of adaptation situations

Approach

 Imperative approach with a composition language

Proposition

 COSMOS middleware  COSMOS DSL  http://picoforge.int-evry.fr/projects/svn/cosmos/

Current interests

 Autonomous distributed context management of mobile devices Adapt to new context data sources, clients, inference rules, etc.  Management of the Quality of context (QoC)

Context-awareness

Objectives

 Middleware to produce and execute distributed context-aware applications for ambiant computing

Approach

 Design: Driven by CA Domain Specific Models

Proposition

 Runtime Models to

 Drive context management  Notify situations Reconfigure applications Update Context Awareness

Current interests

 Distributed observation and reconfiguration  QoC aware contracts

Service Composition Adaptation and Reconfiguration

Objectives

 Ad hoc user task composition in heterogeneous environments considering user preferences  Session continuity of user task (dynamic adaptation at runtime)

Approach

 Mapping of abstract service composition on available components  Monitoring of used HW and SW component properties  Adaptation of the abstract description

Proposition

 Resource (device and component) discovery based

n UPnP

 Dynamic device and component selection  Framework for distributed dynamic monitoring of environment components  Structural runtime adaptation based on injection of patterns

Current interests

 Stateful components  Adaptation (interfaces, behaviour…)

Autonomic Deployment

Objectives

 Autonomic Deployment (i.e. software deployment without user interaction)

Approach

 Declarative language to describe the deployment constraints  Adaptive Mobile Agents to support the deployment  Distributed resolution of the deployment process

Proposition

 Autonomic Deployment Framework (ongoing work)

Current interests

 Deploy middleware for context management from small to big devices  Deploy on Grids or Clouds
