Abstract :
Abstract-It is common that current mobile devices are equipped with multiple interfaces such as GPRS or UMTS for wireless WAN (WWAN) link as well as WiFi and/or bluetooth for local networking. Meanwhile, it is also possible that a number of mobile subscribers keep close for a period of time and fetch and play same live stream from Internet. Stimulated by these facts, we develop C5, a Collaborative Content fetching scheme for Common Characteristics Community, which employs a small scale P2SP framework of a hybrid mobile network and a set of application-level fetching procedures to enable collaborative streaming. The chunk selection strategies are particularly investigated in this paper. Simulation results show that C5 can provide better playback performance in the live streaming application for community members than individual fetching. Thus it can improve the user experiences for mobile Internet subscribers.
