Abstract:
Internet of Things (IoT) platforms interoperability is a major issue in current IoT scenarios. There are different mechanisms to achieve interoperability and Open Geospatial Consortium (OGC) with Sensor Web Enablement (SWE) block of standards like Sensor Observation Service (SOS) has provided the ability to interoperate at different layers, following a centralized approach. However, IoT nature is distributed and a new approach is needed. At the same time, current SOS implementations provide several services and components that are rarely used and affect performance, and are mainly focused for large sensor deployments. In this paper we propose a lightweight SOS design, named SOSLite, based in the OGC consolidated SWE standards able to be executed in low resources devices (e.g. RaspberryPi) and allow fast interoperability and scalability. The proposed use case in which the proposed system has been tested is m-health and concretely ambient assisted living.
