However, existing software for web-based learning does not deal with new technological constraints that mobile devices bring with. Therefore, a new generation of applications for the learning domain that works on these restrictive mobile environments has to be developed. For this purpose, we introduce CARLA, a cooperative learning system that is designed to act in hybrid wireless networks. As a cooperative environment, CARLA aims to disseminate teaching material, notes, and even components of itself through both, the fixed and mobile network to find interested nodes. Due to the mobility of nodes, CARLA deals with upcoming problems as network partitions and synchronization of teaching material, resource dependencies, and time constraints.
