We propose a mobility enhancement method in which APs periodically change their RF channels in a predetermined order that prevents overlap of neighboring APs' channels. Improvement in the throughput is also achieved by manipulating the DCF uplink mode and the Downlink mode. A performance evaluation shows that the proposed scheme is superior to IEEE 802.11 WLAN in handoff delay and throughput.
