SOSLITE: Lightweight Sensor Observation Service (SOS) for the Internet of Things (IOT)

The importance and reach of sensors networks grows every year, however, there are still many challenges that must be addressed. One of them, is the standardized interchange of information that enable interoperability between different networks and applications. To answer this challenge, the Open Geospatial Consortium (OGC) has created the Sensor Web Enablement (SWE) specification. SWE has given place to different mature implementations for the enterprise sector; however, they are usually over dimensioned alternatives that require robust systems. This differs from the capacity of small sensors networks like those used in domotics or eHealth, which are part of the Internet of Things (IoT). This work proposes a Sensor Observation Service (SOS) implementation, which is one of the fundamental components of the SWE specification, that fits small sensors networks environments and that does not require very robust systems to operate, thus providing a standard and agile platform. This implementation of the Sensor Observation Service provides independence from manufacturers and heterogeneous sensors networks, increasing interoperability because information is transmitted in a standard structure and through well-defined software interfaces. It also allows installation in devices of small capacity and low power consumption, reducing deployment costs and encouraging massive deployment of sensors networks and the Internet of Things (IoT).
