Abstract(in English) | CSMA/CA is a well-known medium access mechanism which is employed in the IEEE 802.11 standard for wireless local area networks (WLANs). In CSMA/CA, the WLAN throughput is degraded as a number of stations (STAs) increases due to frame collisions. To solve this problem, we have proposed a visual recognition-based medium access control (VRMAC) mechanism which uses LEDs and cameras. In VRMAC systems, STAs transmit an access request frame by blinking LEDs and an access point (AP) transmits a control frame to allow the STAs to transmit a data frame. Our previous studies only focus on single-cell WLAN. This paper expands VRMAC to be applicable for the case where the VRMAC employed WLANs densely exist. We propose a collision avoidance mechanism using AIFS for VRMAC and evaluate the throughput performance by using a network simulator. |
