Abstract

In the era of information and communication technology, WLANs are being used for military, multimedia and health application, where high system performance and the ability to stay in link is extremely required. WLAN supports best-effort service at lower investment and cost. Apart from low cost ,IEEE 802.11 technology is relatively easy, quick to install , and operating on a unlicensed frequency of 2.4 GHz which can be built independently by the individual or organization without reliance on operator. With the increasing demand and penetration of wireless services, users now expect good Quality of Services (QoS), in terms of delay; media access delay, throughput, and retransmission attempts. The author has studied the effect on Security by changing number of nodes, changing data rates and changing attacks. The effects of variation of these parameters on Throughput, Average Jitter, Average End to End Delay, Peak Queue Size and Average Queue Length have been studied Throughput of CCMP Security Protocol is more by 13.3% in comparison to WEP Security Protocol. In CCMP Average Jitter and Average End to End Delay are lesser by 7.4% and 10.24% respectively in comparison to WEP Security Protocol. This simply proved that CCMP Security Protocol is provides better security in comparison to WEP Security Protocol and remove the flaws of WEP Security Protocol. Wormhole Attack and Eavesdrop Attack badly affected the performance of IEEE 802.11 WLANs. Throughput in wormhole attack reduces by 17% in comparison to eavesdrop attack. Average Jitter and Average End to End Delay reduces by 14% and 8% respectively in Eavesdrop Attack in comparison to Wormhole Attack.
