WSN as a Tool for Supporting Agriculture in the Precision Irrigation

摘要

The Wireless Sensor Networks (WSN) are composed of many devices, called sensor nodes. Such nodes are able to perceive changes in the environment and perform certain actions. The current technologies in WSN were specially devised based on results from computational models and using tool as TinyOS e Tossim, united with the resources of a high level programming language, in this case Python and its PyGame library. However, such tools focus only in a specific task, for example, either allow the creation of the architecture structure of the sensor nodes (TinyOS) or simulate the WSN behavior in text mode (Tossim). The absence of integrated environments for verifying and validating those networks impairs their advancement. Thus, this work focus its research on the integration of existing computer tools in order to estabilish an application development environment for WSN, uniting the robustness of programming languages with the usability of a friendly interface. Many areas can be beneficiated with WSN. Due to the great agriculture potential of northeast Brazil, the application domain in this research is assisted agricultura, once no similar attempt was found in the literature. Therefore, this paper's study case encompasses the developed simulation environment applied to irrigation of soccer fields.
