Desenvolvimento de uma rede de sensores sem fio em topologia mesh utilizando dispositivos IOT

Abstract

Wireless sensor networks carry a large amount of sensors applied in an environment. Through the parameters collected by the sensors it is possible to carry out analyzes, studies and controls on the various physical characteristics present. In order to be able to collect information from sensors, it is necessary to use some intermediate device that can transmit this data to other equipment, the Internet devices of the IOT (Internet of Things) things have these characteristics and stand out because they connect to the internet. The growing presence of sensor networks is favored by radio communication technologies, ie wireless, including Wi-Fi technology. Mesh network topology enables better data traffic in Internet access points are scarce, as all information traffic traverses its participants. It is proposed with this study to develop and evaluate a mesh network of sensors using Wi-Fi as a means of communication in conjunction with the ESP-NOW protocol.
