“…In all scenarios throughput gradually increase as packet size gets higher, except for IPv4 TCP, which drops in speed in packet 896 Bytes to 329Mbps, going down to 313Mbps in packet 1024 Bytes, and then in packet 1152 Bytes increasing again at 316Mbps, this is the only case where throughput had decreased in all scenarios. This was also observed in other research work that graphs are not smooth and could rise and fall a bit as packet size increase [5,7,9], but the overall trend is increasing throughput with packet size. The lowest throughput for 802.11n was 18Mbps (at packet 128 Byte) for TCP IPv6, while 802.11ac lowest throughput was 68Mbps (at packet 128 Byte), a significant increase compared to 802.11n.…”

“…One point of deviation is at Figure5(802.11n) where TCP outperforms UDP on packets 128 and 384 for both IPv4 and IPv6. At low packet sizes, the data obtained had some randomness and this was observed in other studies too[5,7,9]. TCP has lower throughput as it sends acknowledgements, and that it has higher overhead in its packet.…”

“…IPv6 is the latest version of the Internet Protocol (IP), expected to replace IPv4 in the future and addition to providing backwards compatibility, no need for DHCP server, built in encryption, more efficient routing, elimination of NAT (network address translation), better mobility support, better QoS (Quality of Service) and will address IPv4 address shortage [4]. Some related works regarding performance of IPv6 and WLAN IEEE802.11n and 11ac are in [5][6][7][8][9][10][11][12].…”

In this paper, performance of WLAN (Wireless LAN) for peer-peer and client-server networks with WPA-2 security is investigated for both IEEE802.11ac and IEEE802.11n standard. Parameters studied include throughput, and RTT (round trip time) of IPv4 and IPv6 protocols for both TCP and UDP. IPv4 outperform IPv6 in terms of bandwidth and delay due its lower overhead size. IEEE 802.11ac had much better performance than IEEE 802.11n.

“…Unfortunately, decoding a frame in such a short period is not possible. Prior work has shown that the time required to decode a frame is between 200 to 700 when the WPA2 security protocol is used [15,17,22]. This processing time is orders of magnitude longer than SIFS.…”

WiFi networks employ authentication and encryption mechanisms to protect the network from being accessed by unauthorized devices. Therefore, WiFi communication should be possible only between devices inside the same network. However, we have found that all existing WiFi devices send back acknowledgments (ACK) to even fake packets received from WiFi devices outside of their network. We call this behavior Polite WiFi since WiFi devices respond to all packets even those coming from strangers! In this paper, we discover the Polite WiFi behavior for the first time. We also examine this behavior on over 5,000 WiFi devices from 186 vendors. We find that all existing WiFi devices respond to fake packets transmitted to them. We believe this behavior creates many threats as well as opportunities. For example, one can couple this behavior with WiFi sensing and localization techniques to create a new class of security threats. In particular, by continuously sending fake frames to a target device, and measuring the properties of the ACK signal, one can extract sensitive personal information. Similarly, an attacker may use this behavior to quickly drain the battery of WiFi devices by continuously sending fake packets to them. Despite these threats, we also believe that the Polite WiFi behavior can open up new opportunities to WiFi sensing applications by making them more practical and easier to deploy.

“…Some of the related works regarding performance of IEEE802.11ac are as follows. In 2017, Kolahi and Almatrook [8] investigated the impact of WPA2 security on bandwidth and latency in a client-server wireless network using the IEEE802.11ac standard. In 2015, Siddiqui et al [9] investigated the parameters that restrict IEEE 802.11ac from achieving the maximum bandwidth beyond 1Gbps.…”

In this paper, the performance of IEEE 802.11ac wireless LAN using IPv4, IPv6, TCP, UDP, peer-peer, and client-server networks is investigated while implementing WPA2 security. The latest operating systems are used in the study, Windows 10 for workstations and Server 2016 for the server. Packet sizes used range from 128 to 1408 Bytes. Parameters measured were bandwidth, Round Trip Time (RTT), and CPU utilisation. For TCP, client-server WLAN with IPv4 has the highest throughput for all packets, having 105 Mbps for packet size of 128 Bytes and 620 Mbps for packet size of 1408 Bytes while peer-peer with IPv6 had the lowest throughput ranging from 79Mbps for 128 Bytes packet and 335 Mbps for 1408 Bytes packet. For UDP, the highest throughput is achieved again by client-server with IPv4. The bandwidth ranged from 88 Mbps at packet size of 128 Bytes to 808 Mbps for 1408 Bytes and the lowest throughput is that of peer-peer with IPv6, with the lowest of 77 Mbps at packet size of 128Bytes and 403 Mbps for packet size of 1408 Bytes.
