SALSA – A FRAMEWORK FOR CONTEXT-SENSITIVE SERVICE DISCOVERY IN MOBILE COMMERCE APPLICATIONS
Keywords:
Mobile Commerce, Context-Sensitive Service Discovery, Service Frameworks, Service-Oriented Architectures (SOA)Abstract
In an effort to increase the average revenue per user, over the past few years mobile network operators have introduced many new services for mobile devices connected to the internet. However, none of them has proven to be the desired killer application, and many have failed completely. Most of the attention to date has focused on location-aware applications, but the increasingly powerful miniaturized sensors that will probably be embedded in future mobile devices offer many more types of context information than just location. When these additional types of context information are used as well, applications and services can be made much more context-sensitive, and service providers can offer more value to end users. This, in turn, will lead to higher acceptance and adoption of Mobile Commerce services. However, creating context-sensitive applications and services for mobile devices is not a trivial task and developers’ experience with these new kinds of technologies is low. Thus, the development of such services and applications, or the migration of conventional services to context-sensitive services, would be significantly boosted by framework support for client and service development. In this paper we introduce a framework for context-sensitive service discovery that offers systematic development support and reduces the effort involved in migrating from pure information services to context-sensitive services.
