|dc.description.abstract||Wireless networks gain their popularity and fame by providing users with several advantages in accessing information. WLANs provide true mobility and flexibility to users. Another advantage of wireless technology is installation. A physical or cable connection is no longer needed because a single connection to the access point via electromagnetic waves is all that is necessary. This both decreases installation costs and allows wireless networks to be installed in locations where previously it would have been difficult or impossible to install wiring. Such benefits and advantages bring up some security and performance problems. It is imperative to understand the impact of the security mechanisms on the performance of the network. However, the establishment of a trade-off between security and network performance is often neglected. The aim of the research is to quantify the impact of the security mechanisms on the performance of a network. To investigate the effect of multiple security mechanisms on the performance of multi-congested and uncongested networks. The performance effect on different TCP and UDP packet size distributions on secure networks is also studies. The results prove that the security mechanisms affect the network performance in different ways and the more secure the network is, the lower the performance is. The results provide ways in which to configure wireless networks such that security requirements can be met in relation to quantifiable performance impact in practical situations||en_US|
