Scalable Processing of Context Information with COSMOS
[chapter]
2007
Lecture Notes in Computer Science
Preserved Fulltext
These data are used to adapt applications to changing execution contexts. However, legacy frameworks fail to process context information in a scalable and efficient manner. ...
This paper presents COSMOS and evaluates its efficiency throughout the example of the composition of context information to implement a caching/off-loading adaptation situation. ...
To provide a scalable context processing framework, the design of COSMOS has been motivated by three founding principles: separation of concerns, isolation and composability. ...

The identification of these situations is computed from both dynamic context information and domain specific knowledge. ...
This identification is the output of a process involving context interpretation, aggregation and deduction. ...
Notice that, in addition to interactions involving COSMOS supplying MUSE with context data, COSMOS processing nodes can benefit from MUSE ontologies as context sources. ...
