Abstract—This paper presents an adaptive frequency hopping scheme for Wireless Distribution System (WDS) in WLAN with IEEE 802.11g. At least two access points are interconnected to form a WDS to automatically adapt channel by time under synchronization between Master and Slave equipments. This result in a signal’s lingering at a predefined frequency for a short period of time in each channel because of dramatically change to specified channel all the time that protects noise with neighbor channels and avoids intruders which resolves a problem in general form of WDS is vulnerable considering the attacks or interferences due to perpetually use the same frequency channel. Moreover, presents highly secured WPA2 authentication with AES encryption, all above solutions to enhance security level of WLAN in WDS mode.
