Local Shops of Cantanhede Online Platform

This project is an initiative of a group of students of the technical course in management and programming of computer systems, taught at the Technical School of Cantanhede, which will allow consumers, through the Internet, to discover micro and small companies of the city through web pages. The idea came about following the analysis that has been made to the increasing decline of traditional shops and markets because of the increasing of large shopping centers. The project's objectives are to promote trade and proximity services; counteract the trend of exclusive promotion of large commercial groups to digital platforms; and give visibility to small local shops, so that they are able to attract new customers. It should be noted that this project aims to be multidisciplinary and promote a culture of proximity between the localcommunity and the school community, benefiting responsible citizenship.

Performance Evaluation of Proximity Services and Wi-Fi for Public Safety Mission Critical Voice Application

Proximity Services (ProSe) and Wi-Fi are two promising technologies that may provide support for Mission Critical Voice (MCV) applications in remote and rural areas by enabling Device-to-Device (D2D) communication. In this paper, several performance metrics of ProSe and Wi-Fi are evaluated and compared side-by-side under various configurations. The ns-3 simulation results show that ProSe outperforms Wi-Fi in terms of coverage range and access time with a medium traffic load, while Wi-Fi has a shorter access time under a light traffic load. In addition, with various user densities, ProSe offers better coverage range and access time a majority of the time. The evaluation in this paper provides insights to first responders on what to expect with either technology and how to improve the performance by adjusting different system parameters.
