Exhibition's BnB: Intelligent badges and booths for fairs and exhibits

People and companies occupy booths and exhibition areas during fairs and expos. However, visitors may have a difficult time finding where are businesses they are interested on. One way to optimize visitation to fairs and exhibitions would be adoption of intelligent booths, capable of deducting one's interests and pointing locations of suggested projects and products chosen for that specific person. This work describes the architecture and the resources needed to implement such system based on Internet of Things principles.
