SOA Interoperability for Large-Scale Pervasive Environments

Since years, the infrastructural support of pervasive environments like intelligent rooms and houses is an active matter of research. Corresponding projects have been agreed upon service-oriented architectures (SOA) to be used for a most flexible and transparent integration of existing services and applications in those scenarios. But, in times of everywhere low-priced internet access as well as ubiquitous use of personal internet clients (e. g. smart phones), former locally constrained pervasive environments become large-scaled. In this paper, we discuss the challenges of SOA for large-scale pervasiveness on an infrastructural level. Furthermore, we introduce an infrastructural model as well as a prototype that partially solves these challenges by using a systematic SOA interoperability concept.
