Reliable communication is crucial for successful deployment of wireless sensor networks. Therefore, it is important to understand the impact of environmental conditions on the performance of the radios (Chipcon CC1000 transceivers) used in typical sensor nodes. This paper reports on an extensive set of measurements taken in a potato field, where the foliage has an important effect on the propag...

A Wireless Sensor Networks is a network formed with sensors that have characteristics to sensor an area to extract a specific metric, depending of the application. We would like to analyse the feasibility to use sensors in a coffee crop. In this work we are evaluating routing protocols using real dimensions and characteristics of a coffee crop. We evaluate, through simulation, AODV, DSDV and AO...

This paper proposes an automatic expert system for accuracy crop row detection in maize fields based on images acquired from a vision system. Different applications in maize, particularly those based on site specific treatments, require the identification of the crop rows. The vision system is designed with a defined geometry and installed onboard a mobile agricultural vehicle, i.e. submitted t...
