This is an excellent forum for presentations and discussions of the latest results of projects and development research, in several areas of knowledge, in scientific and technological scope.
This event seeks to bring together researchers, students, and professionals from the industrial and academic sectors, seeking to create and/or strengthen the linkages between issues of joint interest, promoting in this way the technology and innovation nationwide. Participants are invited to submit research papers, case studies, articles of opinion or posters, showing studies, methodologies and results achieved in scientific level research projects, completion of course work for graduation, dissertations, and theses.
Jointly with the BTSym’2017 will occur the 7º Workshop Smart Grid Energia, this union aims to provide to the visitors a wide range of option with lectures of companies, organizations, and institutes of technology.

O objetivo e que o protocolo proposto crie um mapa da rede de sensores, analisando as condi-coes do ambiente de funcionamento, visto que os valores de RSSI sao diretamente afetados pelos fenomenos que atuam sobre o sinal de radio. No contexto deste trabalho, o algoritmo de localizacao nao tem o objetivo de encontrar a posicao fisica exata do no sensor, mas sim fazer a rede se adaptar ao ambiente, ja que as posicoes calculadas usando os valores de RSSI cole-tados serao afetadas pelos efeitos de degradacao de sinal existentes. A proposta visa ser uma alternativa a protocolos adaptativos existentes, que usam o monitoramento dos valores de RSSI entre os sensores existentes em uma rede, buscando se adaptar ao meio. O trabalho e composto de simulacao e experimental. Os resultados mostram que a estrategia adotada pelo protocolo descobre rotas de comunicacao eficientes, com uma menor quantidade de troca de mensagens de controle e um menor consumo de energia, se comparados a outra tecnica que usa o monitoramento dos valores de RSSI entre os enlaces.

Distance‐learning will have a direct impact on the training of professionals that will develop the bespoke Internet of Things (IoT) solutions that homes, offices, companies, and cities are increasingly dependent on. Regardless, the training for IoT needs to consider the particularities of wireless communications, as it is essential to guarantee communication in any IoT solution. However, this training is hindered by the difficulty of conducting remote experiments that reproduce the wireless channel behavior. Besides, learning the main theoretical concepts of wireless connectivity would be facilitated by the adoption of practical methods centered on the student, the so‐called inductive training methods. This paper presents a remote, low cost, open‐source network emulation environment capable of reproducing the behavior of nonguided, low‐power links under different configurations. The emulation environment incorporates inductive approaches in the experimentation with wireless connectivity while following a consolidated project methodology. This environment was offered at a postgraduate course in the first semester of 2020. An end of course survey with the students indicated that the environment contributed to the comprehension of the principles governing the over‐the‐air connectivity. The evidence suggests that this remote environment is a useful tool for academic investigations of the particularities of low‐power wireless channels.

IoT has been notoriously troublesome for teaching due to its multidisciplinary nature, involving fields such as computing, electrical engineering, business, humanities studies, and others. Several methodologies have been developed to teach IoT and create solutions, including the Three Phase Methodology (TpM). This paper presents the development of an Integrated Digital Learning Environment (IDLE-IoT), for distance teaching of IoT, based on TpM and Bloom's Taxonomy, integrated with a hardware platform.

The development of IoT solutions depends on the integration and collaborative work between professionals from all of these areas. This has led to the development of methodologies to teach IoT, such as the three‐phase methodology (TpM). This study presents a collaborative system that operationalizes the use of the TpM, aiding in the process of teaching IoT. This system guides and integrates teams developing IoT solutions while providing easy and structured access to information about the project. The system has been used in short and graduation courses. The results have demonstrated its efficiency in assisting students to develop solutions while applying the TpM.

In the same way, IoT applications are becoming a driving force in the economy, playing a central role in many businesses. This scenario presents challenges in the teaching and designing of IoT applications due to its inherent multidisciplinary nature, with areas of knowledge ranging from electrical and computing engineering to those related to the target application to the business itself. In this article, we present a teaching methodology that relies on the project-based learning approach and makes use of a six-layer IoT Open Reference Model that covers all aspects of an IoT solution, from sensors to the end-user interface. The proposed methodology focuses on a complete understanding of the business behind the application and on the end-user needs. Following a top-down approach, from the business to the devices required to collect the necessary information, the approach allows students to have a complete view of all components involved in any IoT application. The proposed methodology has been applied in graduate and extension courses at the University of Campinas and has proven extremely useful.
