WLAN (Wireless Local Area Networks) are gaining their grounds, and widely deployed in organizations, college campuses, public places, and residential areas. This growing popularity of WLAN makes these networks more vulnerable towards attacks and data thefts. Attacker attempts unauthorized access to the network for accessing the sensitive data of the users. Thus, it's necessary to address all the security challenges and its countermeasures using various encryption algorithms to prevent the attacks. However, with the use of security protocols the performance of the WLAN network can be varied. Thus this paper addresses the impact of various security protocols on the WLAN network, keeping throughput as the benchmark for network performance.
IEEE 802.11 ac is the latest wireless standard that operates in 5 Ghz frequency band with higher data rate, compare to its previous standards. This research has also chosen IEEE 802.11 ac standard for investigating the impact of security protocols including WEP (Wired Equivalent Privacy), WPA (WiFi Protected Access), and WPA2 (WiFi Protected Access 2) on throughput of WLAN IEEE 802.11 ac in Windows environment using TCP and UDP traffic for both IP versions (IPv4 & IPv6). The research was launched in a real test-bed setup, with a Client/Server network structure. The results from the experiment showed that the performance of data throughput in the open system were higher comparable to secured systems. However, the results demonstrated that the performance of throughput have different behavior to different security protocols under TCP/UDP traffic with IPV4 & IPV6. A detailed comparison of results in all scenarios is explained in the paper.
