abstract
- Besides services traditionally available in wireless networks, new ones may be offered that transparently adjust and adapt to the user context. The user would have more choice and flexibility if not only could he use platform and third-party services, but also compose his own services in an ad-hoc way, making it available to other users, involving them collaboratively in the construction of a wide set of services. Moreover, collaboration among users can be fostered by the availability of awareness services in mobile environments that enable them to execute joint tasks and activities. This paper presents iCas, an architecture to create context-aware services on the fly, and discusses its main modules. Also a collaborative application scenario is briefly described.
