A collaborative model for representing wireless sensor networks' entities and properties

Wireless sensor nodes are, typically, resource limited. Therefore, the major functions of the Wireless Sensor Network (WSN) cannot be accomplished without collaboration among sensor nodes. In this paper, we present the Wireless Sensor Networks Supported Cooperative Work (WSNSCW) model. The key contribution of this model, when comparing to other models, is allowing for the representation of all the components and properties of a WSN. We also present the main entities and properties of this graph-based model, as well as its formalization.info:eu-repo/semantics/publishedVersio

An integrating platform for environmental monitoring in museums based on wireless sensor networks

Monitoring the museum’s environment for preventive conservation of art purposes is one major concern to all museums. In order to properly conserve the artwork it is critical to continuously measure some parameters, such as temperature, relative humidity, light and, also, pollutants, either in storage or exhibition rooms. The deployment of a Wireless Sensor Network in a museum can help implementing these measurements in real-time, continuously, and in a much easier and cheap way. In this paper, we present the first testbed deployed in an Contemporary Art Museum, located in Madeira Island, Portugal, and the preliminary results of these experiments. On the other hand, we propose a new wireless sensor node that offers some advantages when compared with several commercially available solutions. Furthermore, we present a system that automatically controls the dehumidifying devices, maintaining the humidity at more constant levels.info:eu-repo/semantics/publishedVersio

Towards a collaborative model for wireless sensor networks

Collaboration is crucial to Wireless Sensor Networks (WSNs) as a result of the typical resource limitations of wireless sensor nodes. In this paper, we present a model of collaborative work for WSNs. This model is called Wireless Sensor Networks Supported Cooperative Work (WSNSCW) and was created for these specific networks. We also present the formalization of some entities of the model and its properties. This is a generic model that is being used as a basis for the development of a 3D awareness tool for WSNs.info:eu-repo/semantics/publishedVersio
