Extended Research on Effects of Encryption and Topology on Performance of IEEE 802.11a Laboratory Links.

The increasing importance of wireless communications, involving electronic devices, has been worldly recognized. Performance is an essential issue, leading to more reliable and efficient communications. Security is also critically important. Laboratory measurements were performed about several performance aspects of Wi-Fi IEEE 802.11a WPA2 and WPA point-to-multipoint links. Our study contributes to the performance evaluation of this technology, using available equipments (HP V-M200 access points and Linksys WPC600N adapters). New detailed results are presented and discussed, namely at OSI level 4, from TCP and UDP measurements: TCP throughput, jitter and percentage datagram loss. Comparisons are made to corresponding results obtained for WPA2 and WPA point-to-point, and Open links. Conclusions are drawn about the comparative performance of the links. [ABSTRACT FROM AUTHOR]
