Abstract :
The MAC protocol of HIPERLAN type 2 is based on TDMA/TDD and resources in one MAC frame can be allocated dynamically by the access point (AP). We propose an adaptive random channel (RCH) allocation scheme for HIPERLAN type 2. The AP scheduler controls the number of RCHs in one MAC frame according to the 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 RCHs allocation schemes.
