Abstract

This paper investigates the impact of security on the performance of WLAN. More specifically, it analyzes the impact of different encryption techniques used by two security protocols, namely Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) on the throughput and delay over WLAN IEEE 802.11g. Moreover, in this paper, we investigate the effect of encryption on the performance of wireless transmission during the handover process when a mobile device disassociates from one access point and re-associates with another one. In addition, this paper addresses the impact of the use of security in WLAN specifically on voice traffic namely the incurred transmission delay and jitter.
