Efficient Video Streaming Over Wireless Mesh Networks

In this paper, a video-on-demand (VoD) system based on Home-to-Home Online (H2O) for wireless mesh network (WMN) is proposed and studied. Unlike H2O which focuses on the minimization of system storage, we also take the bandwidth usage into account in order to improve system performance. The VoD system mainly consists of three components: a video block replication scheme, a video block discovery scheme, and several enhancements on video block transmission. The enhancements are named Video Block Broadcasting, Peer-to-Peer, and Time-Shifting. A simulation model is built to evaluate the performance of the proposed VoD system against each enhancement in terms of blocking probability. The results of simulations show the potential and limitations of each enhancement.
