| Summary |
Wireless Mesh Networks (WMNs) may rise as a powerful option for supplying broadband services because it allows to deploying network devices without any wiring, which, in turn, results in cost-effectiveness, scalability of extension and easy configuration. WMNs may adopt the IEEE 802.11 protocols as its interface function. IEEE 802.11n has attracted much interest in recent years, since the protocol supports a much higher transmission rate in comparison to the legacy 802.11a/b/g protocol. However, the IEEE 802.11n standard sets a large number of transmission rates and the concept of spatial streams, which result in making controls of transmission rates difficult. Some studies proposed 802.11n rate adaptations to address these challenges. In this paper, we investigate 802.11n rate adaptation employed in Atheros drivers, and propose a method for simplifying 802.11n rate adaptations. The method is experimentally evaluated using outdoor testbeds in Niigata University. |
