IEEE 802.11 wireless LAN security performance using multiple clients

IEEE 802.11 wireless networks have gained increasing popularity in recent times, providing users with both mobility and flexibility in accessing information. Existing solutions for wireless LAN networks have been exposed to security vulnerabilities and previous study has addressed and evaluated the security performance of IEEE 802.11 wireless networks using single server-client architecture and simple traffic models. This research investigated the effect of multiple security mechanisms on the performance of multiclient congested and uncongested networks. The performance effect of different TCP and UDP packet size distributions on secure networks was also studied. The benefits of this wireless network study focus on determining ways in which to configure wireless networks such that security requirements can be met in relation to quantifiable performance impact in practical situations.
