An architecture to provide quality of service in OGC SWE context

Abstract

The aim of this paper is to describe an architecture named SWARCH (Sensor Web Architecture) that provides quality of service in the context of Sensor Web Enablement (SWE) standards. Sensor Web Enablement is a set of standards proposed by OGC (OpenGis Consortium). These standards provide a transparent and interoperable way to access data measured by sensors. Thus, SWARCH adds to these features of the SWE standard ways of service selection that meet several quality requirements such as response time, availability of sensors, measurement reliability, among others. Quality requirements are defined by users and a broker in the architecture. This broker allows appropriate selection of the sensor network that matches to the QoS parameters. To validate our results, a case study showing reductions up to 50% and 25% in access times to SOS and SES services are presented. © 2013 Springer-Verlag.
