Contribution of the Internet of Things to agricultural education and breeding in rural areas of African countries in conflict: case of the Central African Republic

In this article, we propose a distance learning platform, coupled with traditional pedagogical programs to students and teacher-researchers of the University of Bangui, in particular the Higher Institute of Rural Development (ISDR) of M'Baiki. This platform guarantees data security thanks to WireGuard, which uses proven encryption protocols and algorithms to protect data. Access to resources is efficient thanks to the coupling of the WireGuard VPN server and the Guacamole server. The Moodle LMS platform allows remote access to course materials. BigBlueButton allows the realization of virtual classes. The realization of a part of the distance education programs requires that the actors are in the same local network. In our case, the actors are in different subnetworks which have different public and private addresses. In the logic, the actors who are geographically distant in different subnetworks do not have to communicate and carry out practical and other work. To overcome this limitation, we have configured the tunnel of the WireGuard VPN server coupled to the VXLAN. In some cases of practical work, we will have to be at layer 2 of the OSI model or the WireGuard VPN server uses layer 3 of the OSI model. To move the WireGuard VPN server tunnel from Layer 3 to Layer 2 of the OSI model, we used the coupling of the WireGuard VPN server with VXLAN technology. The features of this platform allow students and teachers to follow courses, tutorials and practical work at a distance applied to the Internet of Things technology. The inclusion of this distance learning platform in the ISRD's pedagogical program makes it possible to have part of the teaching program both face-to-face and at a distance. It also makes it possible to keep all the traditional teaching modalities.
