A new distributed medium access control (MAC) protocol-Soft Reservation Multiple Access with Priority Assignment (SRMA/PA) protocol-is introduced for supporting the integrated services of real-time and non-real-time applications in mobile ad-hoc networks. The SRMA/PA protocol allows the distributed nodes to contend for and reserve time slots with RTS/CTS-like "collision-avoidance" handshake and "soft reservation" mechanism augmented with distributed and dynamic access priority control. The SRMA/PA protocol realizes distributed scheduling for guaranteeing QoS requirements of integrated services and maximizes statistical multiplexing gain. We have demonstrated by simulation studies that the multiplexing gain can be improved significantly without unduly compromising on system complexity. Moreover, we have shown that the proposed back-off mechanism designed for delay-constrained services is useful for further improving utilization of the channel.
