Construcción de un prototipo de red inalámbrica de georreferenciación y generación de alertas para turistas en un área de la Reserva de Producción Faunística Chimborazo.

Abstract

The design and construction of a prototype of wireless communication for the georeferencing and generation of warning messages were made when the life of visitors in the area of the Chimborazo Fauna Production Reserve, it is in danger. Composed by: Sensor Node, Router Node and Coordinating Node. The network was structured with the mesh-type topology, which allows obtaining the information of georeferencing, speed, height obtained from the GPS and the alerts generated by the user. An application was developed in the Visual Studio Community packet that allows the administrator to enter the information of the carriers to a database as well as the route automatically, showing it in a georeferenced map, the graphical interface allows the search of the stored information and its export. Based on the tests carried out, it was demonstrated that the prototype implemented can cover 500m2 in mountainous terrain and 4500m2 in flat terrain with a reception power between -72.3 dBm and -75.9 dBm, showing a reception margin between 28.7 dB and 25.1 dB. The network has a capacity of 128 devices covering 213% of the current capacity required. The GPS device has an error of location of ± 2.5 meters, speed of ± 0.1 m / s and height of ± 20 meters in normal conditions showing that the prototype does not incorporate error to the sensors and that it is reliable. The energy autonomy is 16 hours covering 400% of the normal time of a visitor's journey. It is concluded that the prototype implemented can become a tool, to facilitate the location of people requiring assistance within the Reserve, thus fulfilling national security objectives. It is recommended more research to miniaturize the prototype and thus to improve its portability.
