Abstract: This paper suggests a new adaptive predictive random access channel assignment algorithms utilizing in WLAN/WPAN and describes the assignment processing of the algorithms. As a concrete example, the paper simulates the algorithms in HIPERLAN/2. Compared with other methods, the result of simulation indicates that this new adaptive predictive method decreases the number of collision and increases access efficiency. The algorithms utilizes wireless resource effectively and improves the performance of the system.
