Research vessels are complex data acquisition systems, consisting of a large number of instruments and sensors producing complex observations for many different disciplines. The data and general metadata produced, is commonly disseminated using well ...

Recently, many tools have emerged to manage sensor web data using Semantic Web technologies for effective heterogeneous data integration. However, a remaining challenge is how to manage the massive volumes of sensor data in their semantic form, i.e., ...

Smart transportation planning is one of the fundamental components of Smart Cities. Agent-based transport simulations are one efficient way to support the development of smart transportation planning systems. However, to be reliable, transportation ...

The paper presents two systems called PATS and SAP that when integrated realize Sensor Web Enablement (SWE) of spatially distributed mobile sensors. The Personal Alert and Tracking System (PATS) consists of a networked collection of custom-designed low-...

Recently, sensor webs have been increasingly used to monitor and sense a multitude of observations for various applications, from simple phenomena, such as air pollution measurements, to complex events, for instance perimeter security, or effluent ...

Monitoring the environment is critical for scientists to understand the environmental dynamics. However, the traditional monitoring systems such as sensor networks are usually labor-intensive and complicated to deploy. As the concept of citizen sensing ...

The emergence of a variety of new sensing technologies including geo-sensor networks, cameras or RFID-based systems raises the need for efficient measurement data storage and retrieval. This paper illustrates the suitability of NoSQL databases for ...
