Abstract(in English) To establish the private channel for area owner's wireless local area network (WLAN) systems, virtual dedicated channel scheme has been proposed. In the scheme, guard stations spatially distributed in the private space send network allocation vector (NAV) frames periodically. Periodic NAV frames notify the medium reservation period to the visitor's BSS (Basic Service Set), and the visitor's BSSs that hear NAV frames defer the access to the medium. This scheme prevents the access from visitor's BSS, and the area owner can occupy a certain amount of radio resources. However, when the AP and the stations of the area owner's BSS transmit in the traditional DCF (Distributed Coordination Function) manner within the occupation period, radio resources are wasted due to collisions of data frames. In addition, because of contention-based channel access nature, DCF is unsuitable for transmitting traffic with Quality of Service (QoS) requirements. As a countermeasure against this problem, in this report, we propose a centralized medium access control (MAC) protocol for WLAN system using virtual dedicated channel scheme. Numerical results confirm that the proposed scheme realize more efficient use of radio resources.
