METHOD FOR PRIORITY-BASED BACKOFF NUMBER ASSIGNMENT IN WIRELESS LOCAL AREA NETWORK UNDER DISTRIBUTED COORDINATION FUNCTION

摘要

The present invention, DC to be, the back-off number assignment method according to the priority-based backoff number allocation method for F. WLAN to distinguish between stations according to the priority of the service to the plurality of service classes not overlap each other for each class of service, that defines the contention window, and generates a random back-off number, to the extent predetermined contention window defined by class. As a result, the high-priority class, priority is always generated a small back-off number, the lower classes, the transmission efficiency of the multimedia data of high priority, such as audio or video in a dish F. way is not suitable for real-time applications a it is possible to increase at the same time to avoid delays or pauses of the multimedia data in advance, increasing the performance of the entire system that effectively.
