For the successful ubiquitous environment, the channel management scheme for reducing the interference in wireless LANs environment is very important. And as the IEEE 802.11 family becomes popular, performance decline due to interference of network happens to be a brand new issue. In this paper, we introduce a channel management scheme for reducing the interference and maximizing the performance by channel assignment and load balancing. We present a distributed algorithm and the decision making basis for activating channel assignment and load balancing process under the current circumstances, which assumes network is managed by multiple individual manager and collects the channel information with the methods from IEEE 802.11k draft. The proposed scheme reduces the overhead and improves the performance of the network by reducing the number of times of unnecessary channel assignment and load balancing processes. And we test our algorithms with NS simulation and show that the proposed scheme outperforms than the previous schemes.
