Centralized Peer-to-Peer Video Streaming Over Hybrid Wireless Network

Video streaming over wireless network has drawn a great interest. In traditional wireless local area networks (WLANs), when the number of the users and the number of the flows increases, the contention for the wireless channel will lead to packet loss and packet delay. In this paper, we propose a centralized peer-to-peer video streaming over hybrid wireless network to improve the performance of the video transport over wireless Internet. The base layer of the video is transported from the server via the WLAN mode, which benefits the centralized management of the video distribution, while the enhancement layers are delivered over the multiple paths via the ad hoc mode, which can reduce the congestion in the access point (AP). The simulation results show that our proposed scheme can achieve a better perceptual video quality compared to the WLAN deployment
