Impact of security on bandwidth and latency in IEEE 802.11ac client-to-server WLAN
Samad S. Kolahi, Abdulbasit Almatrook · 2017
In this paper, wireless 802.11ac client-server network with open system (no security) and WPA2 (Wi-Fi Protected Access 2) security is investigated. The results shows that, by implementing WPA2 security, TCP throughput of IPv4 and IPv6 on average decreased by 16.79% and 10.22% respectively. Throughput for UDP is decreased by 18.07% and 12.99% for IPv4 and IPv6 respectively. For both IPv4 and IPv6, WPA2 wireless security implementation also increases the round trip time (RTT) and CPU Utilization for both TCP and UDP.
