An Evaluation of "Security Services" Schemes for IEEE 802.11 Wireless LAN's Using Qualnet
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 are 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.
