无线局域网已经被广泛部署，并且多个接入点（AP）对于无线站（STA）可能变得更加可用，所述无线站（STA）可以根据某种规则从一个AP漫游到另一个AP。我们专注于一个有效和公平的方式来使用多个AP提供的无线接入资源。特别是，我们主要关注的是开发一种分散的方式，使每个STA独立地选择一个合适的可用AP。一个简单的方法是选择具有最强信号的AP;然而，这需要进一步改进。因此，我们提出了分散的AP选择策略，以实现有效和公平的无线接入资源共享，并通过仿真进行评估。结果表明，所提出的策略，可以通过使用共享每个AP的活跃STA的数量，即使STA采用的策略，只有当进入无线局域网，以获得良好的吞吐量性能。此外，如果STA从一个AP漫游到另一个AP，则可以进一步大大提高总吞吐量和公平性。
Wireless LANs have been widely deployed, and multiple access points (APs) are likely to become much more available for wireless stations (STAs) which can roam from one AP to another by some rule. We focus on an efficient and fair way to use the wireless access resources provided by multiple APs. In particular, our major concern is to develop a decentralized way to enable each STA to select an appropriate available AP independently. A straightforward way is to select the AP with the strongest signal; however, this is shown to need further improvement. Hence, we propose decentralized AP selection strategies to achieve an efficient and fair share of wireless access resources, and evaluate them by simulations. The results show that the proposed strategies can attain an excellent throughput performance by use of the number of active STAs sharing each AP, even if STAs employ the strategies only when entering the wireless LAN. In addition, if STAs roam from one AP to another, the total throughput and fairness can be further improved very much.
