Performance Evaluation of IEEE 802.11a 54 Mbps WEP Multi-Node Laboratory Links

摘要

Wi-Fi is an increasingly important wireless communication technique using microwaves. Performance is a very crucial issue, improving communication reliability and efficiency. Security is also most important. Laboratory performance measurements are presented for Wi-Fi IEEE 802.11 a 54 Mbps WEP multi-node links. Our study contributes to performance evaluation of this technology under WEP encryption, using available equipments (HP V-M200 access points and Linksys WPC600N adapters). The paper gives new results from TCP and UDP experiments in terms of TCP throughput versus TCP packet length, jitter and percentage of datagram loss versus UDP datagram size. Comparisons are made with corresponding results for open links. Conclusions are drawn about the comparative performance of the links.
