摘要	In this paper, we propose a priority (or progressive) linear coding based opportunistic routing mechanism (OR-PLC) for H.264 video streaming over multi-hop ad hoc networks. OR-PLC assigns different error protection priorities to video packets according to their perceptual importance to mitigate error propagation problem so that the video quality is enhanced in receiver. Furthermore, OR-PLC exploits the broadcast feature of wireless medium to improve the bandwidth utility. Compared with other opportunistic routing schemes, OR-PLC reduces the delay by progressive encoding and decoding. The experiments show that our mechanism outperforms two state-of-the-art schemes, i.e., MORE and MP-RTP. It turns out that OR-PLC delivers more than 3.5 dB PSNR gains in average, while using less bandwidth.
