Sensor Nodes and Communication Protocols of the Internet of Things Applied to Intelligent Agriculture

The development of smart agriculture has presented extensive development in recent years, that is why countless proposals have been presented around the world. This high variability of technologies used in the implementation of this type of solutions has generated certain users depending on what types of equipment or communication protocols to use depending on the application case. In this article, the different jobs and technologies used in IoT applied to agriculture are analyzed, comparing their technical characteristics through documentary analysis, simulations of case studies, among others. After this study, the results obtained from the bibliographic and documentary review are described by means of tables, in addition sensor nodes are reproduced with specific technical characteristics such as their communication protocol, energy consumption, degrees of protection of the devices, security of the implemented networks, among others in the Cooja software for the simulation of the case studies. This study provides a methodology for selecting the technology that best suits each type of crop.
