Further, as the bandwidth of wireless technologies have increased, consideration has only recently turned to delivering video over wireless networks. Meanwhile, an emerging new video compression standard namely H.264 is widely accepted. The H.264 standard outperforms all previous video compression, and can deliver high video quality at low rate. However, due to wireless channel characteristics, it is insufficient to merely deliver video data; instead delivery must consider also an adaptation of the video data to the networks specific and particularly network friendliness. In this paper, we address H.264 wireless video transmission over IEEE 802.11 wireless LAN by proposing a robust cross layer architecture which exploits: (i) the new standard IEEE 802.11e MAC protocol; (ii) the H.264 error resilience tools, namely data partitioning. The performances of the proposed architecture are extensively investigated by simulations. Results obtained indicate that our architecture can reliably transport the H.264 video stream, while the actual IEEE 802.11 standard in the same conditions, degrades considerably the transmitted video.","PeriodicalId":379037,"journal":{"name":"Proceedings. 14th International Conference on Computer Communications and Networks, 2005.

A recent result by Appenzeller et al. showed that the size of FIFO queues can be reduced considerably without sacrificing utilization. While Appenzeller showed that link utilization is not affected, the impact of this reduction on other aspects of queue management such as fairness, is unclear. Recently, a new class of low-rate DoS attacks called shrews was shown to throttle TCP connections by causing periodic packet drops. Unfortunately, smaller buffer sizes make shrew attacks more effective and harder to detect since shrews need to overflow a smaller buffer to cause drops. In this paper, we investigate the relation between buffer size and the shrew sending rate required to cause damage. Using a simple mathematical model, we show that a relatively small increase in the buffer size over the value proposed by Appenzeller is sufficient to render the shrew attack ineffective. Intuitively, bigger buffers require the shrews to transmit at much higher rates to fill the router queue. However, by doing so, shrews are no longer low-rate attacks and can be detected by active queue management (AQM) techniques such as RED-PD. We verified our analysis through simulations showing that a moderate increase in the buffer size, coupled with an AQM mechanism is adequate to achieve high link utilization while protecting TCP flows from shrew attacks.","PeriodicalId":379037,"journal":{"name":"Proceedings. 14th International Conference on Computer Communications and Networks, 2005.
