APPARATUS FOR REDUCING CONTENTION IN PRIORITIZED CONTENTION ACCESS OF WIRELESS LOCAL NETWORK AND METHOD USING THE SAME

摘要

An apparatus for reducing contention in prioritized contention access of wireless local network and a method using the same are provided to distribute the contention of devices in a PCA(Prioritized Contention Access) section o reduce contention between devices. An apparatus for reducing contention in prioritized contention access of wireless local network comprises the followings: a PCA(Prioritized Contention Access) section detecting unit(120) for detecting a PCA section from beacons received in BP(Beacon Period); a PCA section division unit for dividing the detected PCA section; a device selecting unit(140) for selecting devices used in the PCA section; and a PCA allocating unit(150) for allocating the divided PCA section in the selected device.
