A new dynamic reservation integrated services multiple access (DRISMA) protocol is proposed for the emerging wireless ATM networks. Compared to other PRMA-based protocols, DRISMA has two distinctive features. First, while each voice station reserves isochronous channels by capturing mini-slots, both the capturing probability and the number of mini-slots per frame are adjusted dynamically to enhance bandwidth utilization. Second, a novel method using pre-mini-slots is proposed to provide an available bit rate (ABR) service such that data traffic can only be transmitted over the residual voice bandwidth. DRISMA has the potential to integrate general constant bit rate (CBR), variable bit rate (VBR) and ABR traffic efficiently over a wireless ATM channel
