Performance Analysis of IEEE 802.11 Wireless LANs

IEEE 802.11 Wireless Networks have gained
popularity, providing users mobility and
flexibility in accessing information. Existing
solutions for wireless LAN networks have been
exposed to security vulnerabilities. Previous study
has evaluated the security performance of
IEEE 802.11 wireless networks using single server-
client architecture. The research presented in this
book investigates the effect of multiple security
mechanisms on the performance of multi-client
congested and un-congested networks. The effect of
different TCP and UDP packet sizes on
performance of secure networks was also studied. The
results showed that WEP encryption
significantly degrades the performance of congested
wireless networks. Network performance
degradation increased as the number of clients was
increased under all security mechanisms.
