Impact of Encryption on the Throughput of Infrastructure WLAN IEEE 802.11g

This paper investigates the impact of security on the performance of WLAN. More specifically, it analyzes the impact of applying encryption used by the well-known security protocol wired equivalent privacy (WEP) on the throughput over an infrastructure WLAN, IEEE 802.11g. This paper also addresses the different issues related to the security protocols currently used in WLAN IEEE 802.11g and demonstrates how these issues affect the final results of the experiments conducted. The main result is that the security adds moderate degradation on the throughput that may affect some applications over infrastructure WLANs.
