Abstract. In this paper we discuss two alternative architectures for service management in IoT and sensor networks. The first one is based on Open Service Gateway (OSGi) framework and Remote Services for OSGi (R-OSGi) bundle. The second architecture extends the notion of REST (Representational State Transfer) paradigm. Main purpose of the extension was to enable efficient, dynamic searching for devices capable of fulfilling certain requests in the scope of actual context, to distribute both the devices and controlling services, to orchestrate the devices to provide complex functionality, and to proxy/standardize the access to the devices' functionality. We found simpler, OSGi-based solution better suited for homogeneous sensor networks, while more complex REST-based framework -- for heterogeneous and widely distributed IoT devices and services.
