Résumé: The MAC protocol of HIPERLAN type 2 is based on TDMA/TDD and resources in one MAC frame can be allocated dynamically by Access Point (AP). We propose an adaptive random channel (RCH) allocation scheme for HIPERLAN type 2. The AP scheduler controls the number of RCH's in one MAC frame according to transmission results of the previous MAC frame. The simulation results show that the proposed scheme achieves higher efficiency of resource and lower access delay than fixed RCH's allocation schemes.
