next generation mobility applications: a wireless cooperative access architecture

Accessing cellular networks for downloading large-size contents is a common task performed from modern smart phones. Nevertheless, several problems need to be addressed in order to provide an acceptable quality of experience to the final users. This paper presents a smart phone application aiming at reducing both cellular network load and file downloading time by leveraging network resource sharing. Groups of neighboring devices are formed depending on geographical position and battery consumption. WWAN and WLAN are then shared under an altruistic cooperative scenario for an increased user experience when accessing multimedia content.
