Performance Comparison of IEEE802.11a, IEEE802.11b, IEEE802.11g and IEEE802.11n in Multiple Routers

Nowadays, WLAN (Wireless Local Area Networks) has evolved into one of the most auspicious and lucrative technology. The most prominent use of the application of wireless network technology is 802.11 WLAN. IEEE 802.11(Institute of Electrical and Electronics Engineers) standard specified the frequencies of different WLAN standards. The aspiration of this research is to scrutinize and compare the performance of different wireless LAN standards for the increasing number of routers in a predefined area. For evaluating the performance Wireless LAN throughput, wireless LAN load delay, and wireless LAN media access delay metrics are used. For all combinations of the number of routers, IEEE802.11b shows the highest and IEEE802.11n shows the lowest WLAN media access delay and average wireless LAN delay for 64 nodes.
