在广泛使用的IEEE 802.11标准中，所谓的性能异常是众所周知的问题。一些作品试图解决这个问题，通过引入机制，如数据包碎片，回退适应，或数据包聚合在一个固定的时间间隔。在这篇文章中，我们提出并深入分析PAS，一个动态的和分布式的方法来解决性能异常的问题。PAS基于使用动态时间间隔的分组聚合，该动态时间间隔取决于每个节点感知的无线信道占用时间。由于每个站独立地感测介质，这使得PAS成为完全分布式的解决方案。甚至，PAS可以与标准IEEE 802.11节点共存，而无需任何特定的适配，还能够提高性能。我们的解决方案不同于文献中的其他命题，因为它的动态和分布式的性质，这使得它适合在多跳网络的背景下。此外，它允许增加公平性，反应性，以及在某些情况下的效率。在这篇文章中，我们深入分析和强调我们的建议的绩效评估。
In the widely used IEEE 802.11 standard, the so-called performance anomaly is a well-known issue. Several works have tried to solve this problem by introducing mechanisms such as packet fragmentation, backoff adaptation, or packet aggregation during a fixed time interval. In this article, we present and thoroughly analyze PAS, a dynamic and distributed approach solving the performance anomaly problem. PAS is based on packets’ aggregation using a dynamic time interval, which depends on the wireless channel occupation time perceived by each node. Since each station senses the medium independently, this makes PAS a totally distributed solution. Even more, PAS may coexist with standard IEEE 802.11 nodes without any particular adaptation, yet being able to improve performance. Our solution differs from other propositions in the literature because of its dynamic and distributed nature, which makes it suitable in the context of multi-hop networks. Furthermore, it allows increasing fairness, reactivity, and in some cases efficiency. In this article, we thoroughly analyze and emphasize the performance evaluation of our proposal.
