8. 3 June, 2015 ASNA research 8 Context-aware applications Context information can be used to characterize the situation of an entity of interest for the application Goal: use real-world situation to influence the behaviour of applications on behalf of their users Context information Context-aware application context Real world context modelling influences

9. 3 June, 2015 ASNA research 9 Context examples Location (multi-domain sources) Speed, direction Role (home, work) Activities (meeting, busy, travelling) Surroundings (type of place, luminance) Connectivity (bandwidth, delay) Availability Medical/health parameters (emergency) Resources in the neighborhood (printers, displays, speakers)

10. 3 June, 2015 ASNA research 10 Personal Area Network (PAN) Applications Context in AWARENESS How can we detect context? How can we derive/reason context? How can we use context? How can we keep it secure and private? GPRS, UMTS, Wi-Fi Internet Ad-hoc networking Mobile user, Mobile applications Mobile user, Mobile applications AWARENESS service and network infrastructure Applications M-health services

11. 3 June, 2015 ASNA research 11 Modelling, reasoning, inference, quality of context Support for context-aware applications –ECA rules, rule engines –Application framework –Context sources (implementation and simulation) Ad hoc networking for e-health applications And many more… Topics for assignments

12. 3 June, 2015 ASNA research 12 Model-driven service development Main goal: enable rapid service development Concentrate on Freeband services  mobile, context-aware and attentive Hypothesis if we have proper models, we can define transformations to implementations on different platforms (model-driven engineering)

15. 3 June, 2015 ASNA research 15 Necessary support abstract platforms modelling languages transformations service designers’ view (service creation phase) service specification service design middleware notify location traffic info I know how context- aware services can be defined, built and deployed! I also know the technology! service realisation preferred means notification A-MUSE Service Engineering Utility service providers’ view (service execution phase) service users’ view (service execution phase) experts’ view (preparation phase) I have this idea for a service and I want to build it!

16. 3 June, 2015 ASNA research 16 Semantic web Current web is limited to syntax-based interactions There is a need for semantic information if machine-to-machine interactions are enabled Solution: use of ontology-based languages (Semantic web) Semantic web services: service discovery, mediation and composition using ontology-based techniques

17. 3 June, 2015 ASNA research 17 Topics for assignments Behaviour modelling Model transformations Modelling and transformation tools Mapping to concrete platforms Service modelling Service composition And many more…
