In this paper, we present, a Time-based Opportunistic Relay (TOR) scheme for high-quality video streaming over WLANs. The proposed scheme exploits path diversity in relaying packets with awareness of the time constraints of video data. Specifically, relay nodes continuously overhear and opportunistically forward packets to enhance end-to-end delivery rates. To relay a packet in a time-aware manner, a relay deadline is computed for each packet and used by relay nodes to determine whether they should relay or discard the packet. Simulation results show that TOR improves video quality by up to 9.76 dB. | Source Title: | Proceedings of the 2007 IEEE International Conference on Multimedia and Expo, ICME 2007 | URI: | http://scholarbank.nus.edu.sg/handle/10635/146260 | ISBN: | 1424410177 9781424410170 |
