Sagade Abstract - Service-Oriented Architecture (SOA) consists of autonomous, standardized, and self-describing components known as services that communicate with each other and are provisioned as per the rules decided. This architecture is being widely used worldwide. SOA is verified for dynamic, automatic, and self-configuring distributed systems such as in automation systems. This paper explores SOA paradigm for active spaces in an IoT environment with devices realized by device profile for web service (DPWS) wherein the context information is acquired, processed, and submitted to a composition engine so as to provision relevant services which suit to the context. Identification of profiled users in the context is achieved using RFID tags accordingly composition plans are created for every user. A six-phased composition process is employed to complete this task. DPWSim simulator is deployed for illustration and testing the system. WS4D explorer is used to scan the available devices in the network. IoT platform is employed for providing context information notifications comprising of various sensors and IoT environments.
