The Impact of Human Shadowing/Movement on Performance of 802.11ac Client-to-Server WLAN

Abstract

This paper investigates the impact of human movement on 802.11ac WLAN performance using IPv4, IPv6, TCP and UDP protocols. The results show that on average, the TCP and UDP on WLAN with human movement has a lower throughput than non-human shadowing for both IPv4 and IPv6. For IPv4, the presence of human movement decreases TCP throughput by 12.76% and UDP throughput by 9.66%. For IPv6 with human movement, TCP and UDP throughput reduces by about 13.38% and 8.74% respectively. For both IPv4 and IPv6, the presence of human movement also increases the round trip time (RTT) and CPU Utilization for both TCP and UDP.
