Infostation systems, based on pico-cells, provide intermittent but very high speed rates. Many problems appear because of discontinuous coverage and the mobile environment (mainly service disruptions). These problems directly affect applications performance. In this paper, we propose a hierarchical architecture that enables the network to resolve these problems. A new entity called access controller has been introduced and validated. Then, we focus on applications made possible using this architecture. Mainly, a distributed data storage model is described that proposes many classes of service to give more flexibility to users. Finally, we present a middleware adapted to the architecture that implements the storage model and class of services.
