Wireless sensor networks (WSNs) belong to emerging technologies where network devices can interact with the surrounding environment by sensing physical parameters. Recently, with the dissemination of mobile devices to Internet connectivity, users can interact with sensor networks and collect environmental data, anytime, anywhere using user-friendly mobile applications. Following the Internet of Things vision, the integration of all sorts of Internet-based devices is considered a big challenge. New infrastructures are required in order to interconnect these devices independently of the used technologies. This paper proposes a model for WSNs monitoring based on a REST Web service and XML messages to provide a mobile ubiquitous approach for WSN monitoring. Data collected from a WSN is stored in a database. Then, mobile clients send XML based messages to a HTTP server through a well-defined …
