INTERNET DAS COISAS APLICADA AO GERENCIAMENTO DE PRESENÇA E ENCONTROS DE PESSOAS EM PRÉDIOS INTELIGENTES

With technological advances and the popularization of the Internet of Things (IoT), more concepts of Smart Cities have been adopted in large urban centers,in particular, in smart buildings, that use sensors to better control their facilities. One of the areas of smart buildings is the presence and meeting management that manages the displacement and location of occupants in the building. The detection of people in indoor environments is becoming increasingly useful, espe- cially in times of pandemic, when it is important to identify which people were close to each other in the same place and for how long. Considering this scenario, this study presents a distributed software architecture that uses four components that provide services for storing and consulting data, meeting notifications, and identifying the devices involved. In a flexible way, beacons and Android devices can be used to represent both people and physical spaces. In addition, the proposed architecture enables to determine attendances in real time, calculate the total time of stay, and check meetings of people. The effectiveness of the proposed solution was demonstrated through an experimental evaluation simulating its use.
