Research on Distributed Adaptive Channel Allocation in WLAN

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 modifying 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.
