Investigation on Context-Aware Service Discovery in Pervasive Computing Environments

The increasing transmission of portable devices with wireless connectivity enables new pervasive scenarios, where users require personalized service access according to their needs, position, and environment conditions (context-aware services). A fundamental requirement for the context-aware service discovery is the dynamic retrieval and interaction with local resources, i.e., resource discovery. The high degree of dynamicity and heterogeneity of mobile environments requires moving around and/or extending traditional discovery solutions to support more intelligent service search and retrieval, personalized to user context conditions. We have reviewed the research of context aware service discovery that based on semantic data representation and technologies; allow flexible matching between user requirements and service capabilities in open and dynamic deployment scenarios.
