Abstract: Video is becoming the dominant traffic over the wireless networks. Given the limited wireless resources, supporting multi-user video streaming with good video playback quality- of-service (QoS) is very challenging. The key difficulties involve providing good playback quality while also satisfy- ing the stringent video packet delay bounds. The allocation of wireless resources need to be efficient and coordination of mobile video users should have a distributed fashion. In this paper we present a distributed framework for multi-user video streaming over an ad-hoc 802.11 like networks. The proposed algorithm is based on a utility-driven scheme that adjusts the video users' sending rates according to APP layer video buffer status. Simulation results demonstrate that the proposed scheme is quite efficient on radio resource while have better QoS than content blind 802.11 DCF scheme.
