An evaluation of IEEE 802.11 mac layer handoff process in CAPWAP centralized WLAN

The growing demand to provide secure wireless connectivity, especially in hot spot areas such as conference halls and events, motivated the development of Control and Provisioning of Wireless Access Point (CAPWAP) centralized Wireless Local Area Network (WLAN). The centralized WLAN utilizes an Ac...
