How Mobility Impacts Video Streaming over Multi-Hop Wireless Networks?

摘要: In this work, we investigate the impact of mobility on video streaming over multi-hop wireless networks by utilizing a class scheduling schemes. We show that node spatial has ability to improve quality and reduce transmission delay without help advanced coding techniques. To describe practical mobile scenario, consider random walk model in which each can randomly independently choose its direction, all nodes identically uniformly visit entire network. The contributions work are twofold: 1) It studies optimal velocity for system. case, it is possible achieve almost constant as number increases; 2) derives an achievable quality-delay tradeoff range different velocities. Therefore, helpful shed insights network design fundamental guidelines establishing efficient
