| Abstract(in English) | IEEE 802.11 WLANs distributed coordination function (DCF) employs a carrier sense multiple access with collision avoidance (CSMA/CA) mechanism. To avoid frame collisions, CSMA/CA uses a back off algorithm in which stations (STAs) wait a randomly determined period of time. The waiting time can be considered overhead. Moreover, even when the back off algorithm is used, collisions still occur. In this paper, we propose a novel media access control (MAC) mechanism for WLAN systems, called visual recognition based medium access control (VRMAC) mechanism. In VRMAC, to facilitate collision-less media access with low overhead, stations (STAs) equipped with LEDs send media-access request messages by blinking their LEDs and an access point (AP) equipped with a camera receives the messages via the camera. Our simulation results show that the mechanism improves WLAN throughput over that of the conventional MAC mechanism in WLANs. |
