Mobile Learning: Hierarchical Architecture: Geographical Location and Routing of Mobile Nodes

This article discloses a system for locating mobile nodes and transfer data in a mobile learning system. The proposed solution is based on organizing cell cellular networks and the geographical coordinates. This means that mobile nodes are located thanks to their geographical position, which allows grouping the nearest nodes in a cell which we call Node Open Digital Space (NODS). In order to better organize the mobile learning system is a server placed at each Open Digital Space (ODS) allowing access to resources. These servers at each ODS are connected to a central server that centralizes all the data to identify the mobile nodes. This hierarchical architecture meets the needs of collaboration and latency reduction in a mobile learning solution that we want to implement in Senegal.
