“…This happens because the contention avoidance mechanism will give all stations the same probability of access to the radio channel, and stations with a lower rate mode need more time to send the same amount of data. The transmission can also experience short loss bursts [6] due to temporary radio perturbation. These loss bursts induce delay spikes due to contention at the MAC level, which in turn may induce losses at the IP level, since the queues at the AP may overflow.…”

Home networks are becoming ubiquitous, especially since the advent of wireless technologies such as IEEE 802.11. Coupled with this, there is an increase in the number of broadband-connected homes, and many new services are being deployed by broadband providers, such as TV and VoIP. The home network is thus becoming the "media hub" of the house. This trend is expected to continue, and to expand into the Consumer Electronics (CE) market as well. This means new devices that can tap into the network in order to get their data, such as wireless TV sets, gaming consoles, tablet PCs, etc. In this paper, we address the issue of evaluating the QoS provided for those media services, from the end-user's point of view. We present a performance analysis of the home network in terms of perceived quality, and show how our real-time quality assessment technique can be used to dynamically control existing QoS mechanisms. This participates to minimizing resource consumption by tuning the appropriate QoS affecting parameters in order to keep the perceived quality (the ultimate target) within acceptable bounds.

“…However, it is interesting to point out some upcoming improvements to wi-fi networks. The 802.11e QoS extensions [6], [39] will allow to define different Access Categories in order to differentiate several service levels during the MAC contention process. It will be also possible to omit the acknowledgements and disable retransmission.…”
