SEMSuS: Semantic middleware for dynamic service-oriented sensor network

Abstract

Sensor network appears to be the technology of the 21st century. Middleware for wireless sensor networks (WSN) acts as the interface point between wireless sensor nodes and higher application layers. A middleware can introduce and enhance access to the underlying networks in intelligent ways. In this paper we present a middleware for wireless sensor networks that uses a set of technical statements, such as patterns and styles, in order to achieve flexibility, compatibility, autonomy and adoption. The middleware exposes the functionality of the network as semantic web services, so that applications can access its functionality through web services. Sensor web combines sensors and sensor networks with a Service-Oriented Architecture (SOA). The Service Oriented Architecture allows us to discover, describe and invoke services from a heterogeneous software platform. Dispatcher and Interceptors are used inside the network. We propose a scenario in which two services are exposed a semantic web services and designed to run in a constrained environment and they are exchanged in accordance with capabilities of the network. © 2013 Springer Science+Business Media.
