中文摘要：

针对目前广泛使用的无线局域网,提出了一种新的分布式自适应信道分配算法。不同于以往的集中式算法,此算法不需集中控制中心,只需要每个AP通过自身对网络的感知与预测自适应地进行调整信道,从而达到整个网络的信道优化分配。较之以往算法实时性强,能对多变的网络状况做出快速反应。首次提出了分级式最佳切换概率概念,在确保算法收敛性的基础上提高了算法的收敛速度。并在不同的仿真环境下验证了算法的正确性和通用性。

英文摘要：

The paper proposes a distributed adaptive channel allocation for the multi APs WLAN. There is no need of control center, which is different from the central - controlled algorithm. It can work effectively through modi- fying the own channel by each AP according to their own detection of the whole network, instead of knowing the whole network＇ s structure and the load. APs can adapt their channels quickly to the time - variable network. The paper also comes up with a new conception named the hierarchical optimal switch probability, which accelerates the algorithm convergence rate. The algorithm is validated in different environment.
