Implementación de un prototipo de sistema de seguridad doméstico basado en WPAN para una red IoT.

Abstract

In this project, the detection of intrusions and gas levels was carried out through a network of sensors and the Internet of Things. The selection of the elements that make up the net was developed based on the essential features according to the requirements. The prototype has five nodes: the sensor node to obtain the information of each sensor, the actuator node, which, through the user, performs a specific action; the coordinating node in charge of receiving information both from the internet connection and from the sensor nodes, interconnecting each other, establishing itself as the central point of the network. Finally, the internet connection node, which is made up of an Arduino and a computer, is responsible for sending or receiving data from the database. For the visualization of the data, a mobile platform application and a desktop application were developed in Microsoft Visual Studio. The prototype works based on the visualization and saving of the information in the database in real time, through the forms.With the help of Wireshark packet capture software, it was possible to define that the prototype has a packet loss of around 71% at a maximum distance of 9 meters with the presence of obstacles. A detection percentage of the motion sensor of 74.71% and imprecision of the gas sensor of 0.027 volts. The use of the wireless sensor network in conjunction with the Internet of Things provides broad applicability. It is recommended to take into account that the system requires a stable internet connection for proper operation.
