The concern about understanding the effects of climate change on the environment, such as the decline of pollinators found in nature, the need to support researchers to run experiments efficiently and to share those results, makes it necessary to study and develop virtual laboratories through the web, in order to gain greater insight on the behavior of bees, which is the main pollinator of plants...
Wireless Sensor Networks (WSNs), are a challenging and evolving area where applications can demand services, distribution, modularity and intelligence. WSNs are a versatile field with varying software architectures, which has led to the development of a plethora of WSN middlewares, management and reconfiguration protocols. To realize the potential of evolving WSN technologies and software architectures...
In wireless sensor networks (WSNs) the position information of individual nodes is a matter of vital importance because allows the implementation of necessary network functions such as routing, querying and other applications. The objective of this paper is to propose an algorithm of three-dimensional distributed range-free localization for WSNs, using an unmanned aerial vehicle (UAV) equipped with...
Saving energy in Wireless Sensor Networks is essential to extend the lifetime of in-field deployments. Previous research has shown that communication is generally the most energy consuming task and needs to be reduced in order to build resource-efficient long-term applications. The communication demand for retrieving query results from deep within the sensor network is typically high. As a result,...
