Experimental evaluation of a grouping method employing network allocation vector based on IEEE802.11 wireless LAN

With the rapid growth in the number of wireless LAN (WLAN) stations (STAs) complying with IEEE802.11 standards, like smartphones, heavy congestion is a common occurrence where many STAs are present. In this paper, to solve this problem, we propose a transmit constraint method that takes account of transmission speed, in addition the number of STAs. The proposed scheme is confirmed by experimental measurements using an IEEE802.11b/g compliant access point (AP). The proposed scheme highly offers effective priority STA protection. These results confirm about two times system throughput higher than conventional scheme.
