On mobile clients as free riders in peer-to-peer live streaming

Mobile devices today such as netbooks, tablet PCs and smart phones provide user-friendly interfaces for people to capture live video. However as a viewer, they prefer not to share downloaded clips due to the limited computing power, upload bandwidth and mostly due to the high power consumption while scheduling segments. In this paper, we discuss the possibility of allowing mobile clients run as free riders under managed usage by assigning a suitable serving peer, and analyze the impact caused by mobile clients on the required bandwidth of our P2P live streaming system, which is a server-enabled architecture that provides client-to-client (C2C) live streaming service.
