The Impact of Security on the Performance of IPv4 and IPv6 Using 802.11n Wireless LAN

The impact of WPA2 security on performance of IPv4 and IPv6 on two client-server wireless 802.1 In networks implementing Windows Vista-Windows Server 2008 and Windows XP -Windows Server 2008 is investigated. Results indicated that for XP enabling WPA2 results in an average of approximately 7.07% less throughput than open systems for IPv4 and 5.42% less throughput for IPv6. Enabling WPA2 on Vista results in an average of approximately 9.39% less throughput than open system for IPv4 and 17.02% less throughput for IPv6. With WPA2 security, IPv4 provides higher bandwidth than IPv6.
