Fundamentals of the Backoff Process in 802.11: Dichotomy of the Aggregation
Since its introduction, the performance of IEEE 802.11 has attracted a lot of research attention and the center of the attention has been the throughput. Recently, other critical performance aspects of 802.11 also burst onto the scene, which include short-term fairness and delay. It goes without saying that there has been a phenomenal growth of Skype and IPTV users and it is reported that an ever-increasing percentage of these users connects to the Internet through wireless connections in US. Remarkably, it is found that jitter is more negatively correlated with Skype call duration than delay, i.e., Skype users tend to hang up their calls earlier with large jitters.
