“…Instead of having intensive work on the programming to control a unit software of a wide variety of sensor devices [5], [6], this project consider a generic mechanism to overcome this need. In addition, a small size and less complex message protocol helps to improve the performance of the sensor network when mobile sensors with processing capabilities limitations are deployed avoiding dependence on a stable network, with no Internet connection.…”

“…However, this architecture, also known as Sensor Bus, does not take into account the following issues: (1) an automatically control and access of different sensor data flow rate and format [5], [6]; (2) keep the sensor status available on the Web in near real-time [7], [8]; and (3) the use of lightweight standard protocols to exchange information between devices and sensor applications when both large volumes of data are exchanged, and devices have limited bandwidth and processing capabilities [9], [10] .…”

“…Open Geospatial Consortium (OGC 1 ) has supported this approach by providing a set of standard activities, rules and guidelines for web-based sensors via the Sensor Web Enablement (SWE) initiative. However, one of the SWE limitations is that it cannot easily be modified and adapted to dynamic scenarios, specially problematic for mobile sensors, because a set of enhanced requirements must hold to control and access different sensor data flow rate and format [5], [6], keep the sensor updates available in near real-time [7], [8], and enable the exchange of large volumes of data between applications and devices with limited capabilities [9], [10].…”

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.
