Abstract :
IEEE802.11a/b/g Wireless LAN (WLAN) supports multiple transmission rates for packet transmission. In a mesh network backbone using WLAN, it is desirable to select and use an optimum transmission rate in order to achieve high throughput. Transmission rate can be set fixedly or adaptively. The former is further classified to link-based and node-based. In this paper, three transmission rate selection methods, link-based fixed optimum rate transmission, node-based fixed rate transmission and adaptive rate transmission are experimentally evaluated. It is shown that the link-based fixed optimum rate transmission method outperforms the other methods in the average throughput.
