摘要： A method for performing an efficient handoff of a wireless endpoint to an access point in a wireless network environment includes measuring a number of stations utilizing the access point, selecting a broadcast count of the wireless endpoint according to the number of stations, selecting a retry count of the access point according to the number of stations, and performing the handoff of the wireless endpoint to the access point utilizing the selected broadcast count and retry count. The broadcast count corresponding to a number of probe request frames sent by the wireless endpoint to initiate the handoff of the wireless endpoint, and the retry count corresponding to a number of probe response frames sent by the access point to acknowledge receipt of the probe request frames.
