| Abstract(in English) | To establish a virtual dedicated channel for area owner's wireless local area network (WLAN) systems, a virtual dedicated channel scheme using periodic medium reservation 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 overhear 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 this scheme is applied to WLAN system operating in 2.4 GHz band, because of the overlapping channels configurations, the NAV frames for notifying the reservation period should be sent to the adjacent channels. Notification of NAV frame to the adjacent channels increases the overhead, and it degrades the performance of area-owner's BSS. In this paper, we discuss the effect of notification NAV frame to the adjacent channels on the performance of area-owner’s BSS. |
