“…Such limitations can be addressed by adopting a generic approach based on existing standard interfaces such as SWE standards and/or Devices Profile for Web Services(DPWS) [17], [18]. Although several applications rely on standard protocols, the communication between sensors and the integration of sensors in highly dynamic scenario in near real-time still is not fully addressed.…”

Abstract-Wireless Sensor Networks (WSN) are often composed of a wide range of sensor nodes, which may vary greatly in their type of hardware platform, as well as their sensing and mobility capabilities. The ability of a sensor to move is a particularly important feature in dynamic scenarios, since mobile sensors can fill the gap caused by the failures of those that are stationary, and thus extend the lifetime and span of a WSN. However, there remains the problems of intersensory communication in the field when integrating mobile sensors into the Sensor Web in dynamic scenarios since it does not have the necessary interoperability for automatically managing the different types of sensor data and activities involved in such scenarios. This paper tackles this problem by adopting an approach consisting of an enhanced messaging protocol and a dynamic sensor management component. In validating the proposal, two different realistic scenarios were simulated to evaluate the achieved results in terms of interoperability and performance. The results provided evidence that the proposal complies with Sensor Web standards as well as being suitable for near real-time data publication, and is thus able to support applications in dynamic scenarios.

“…The main differential of this study was to explore how the componentization of software, mixed with software diversity techniques (N-Versions programming), can be used in WSN both to create self-adaptive lowpower applications and to develop fault-tolerant applications. To achieve different levels of self-organization and fault tolerance, it was necessary to integrate various approaches and solutions previously proposed, among them, the protocol DAARP 16 and the frameworks: FlexFT, 23 OpenCOM, 24 and Sinalgo. 22 The objective of this work was not to develop the best fire detection solution, considering that a strong group of heterogeneous professionals is required in the development process.…”

The wildfires caused by human occupation is one of the factors that most contributes to deforestation of conservation areas, resulting in a number of issues for ecological systems. Premature fire detections lead to the elimination or reduction of the damage that will be caused by a fire incident. Wireless sensor networks have been shown to be a good alternative for environmental monitoring applications, as they can collect and send information in real time, such as humidity, wind, and temperature of various parts of the forest. Due to problems such as power limitation, communication failure, and loss of nodes, the network topology is constantly changing, requiring mechanisms to achieve self-organization and fault tolerance. This article proposes the development of a model and application in self-organizing and fault-tolerant wireless sensor networks for fire detection in conservation areas. To achieve self-organization and fault tolerance, we rely on encouraged local interactions between neighboring nodes that monitor the same region and the coordination of tasks, through a supervisor node, equipped with a framework for developing component-based fault-tolerant applications. For the analysis and validation of both model and application, it was simulated 60 events in the network of sensors in a real scenario using the simulator Sinalgo. The results were classified as True (partial or absolute) or False (partial or absolute). In all, 45% of consensus identified a possible fault in the application and in only 35% there was absolute consensus.

“…This framework allows for the reuse and integration of produced data with other data resources, which enables spatial business intelligence for various domain-specific applications. Similarly, [23] discussed the use of FlexFT, which is a generic component-based framework for the construction of adaptive fault tolerant systems that can integrate and reuse technologies and deploy them across heterogeneous devices.…”

“…FlexFT provided a standardized and interoperable interface for sensor observations by relying upon the "Sensor Web" paradigm established by the Open Geospatial Consortium (OGC). Beder et al [23] implemented a Java prototype to the framework and the authors evaluated the potential benefits through case studies and performance measurements. By implementing and deploying these case studies in standard PCs as well as in sensor nodes, authors showed that FlexFT could cope high heterogeneity with minimal resource overheads.…”

SREQP: A Solar Radiation Extraction and Query Platform for the Production and Consumption of Linked Data from Weather Stations Sensors

Nowadays, solar radiation information is provided from sensors installed in different geographic locations and platforms of meteorological agencies. However, common formats such as PDF files and HTML documents to provide solar radiation information do not offer semantics in their content, and they may pose problems to integrate and fuse data from multiple resources. One of the challenges of sensors Web is the unification of data from multiple sources, although this type of information facilitates interoperability with other sensor Web systems. This research proposes architecture SREQP (Solar Radiation Extraction and Query Platform) to extract solar radiation data from multiple external sources and merge them on a single and unique platform. SREQP makes use of Linked Data to generate a set of triples containing information about extracted data, which allows final users to query data through a SPARQL endpoint. The conceptual model was developed by using known vocabularies, such as SSN or WGS84. Moreover, an Analytic Hierarchy Process was carried out for the evaluation of SREQP in order to identify and evaluate the main features of Linked-Sensor-Data and the sensor Web systems. Results from the evaluation indicated that SREQP contained most of the features considered essential in Linked-Sensor-Data and sensor Web systems.
