A novel protocol under a priority time constraint for real-time communication systems is proposed. This protocol can maintain two priority classes. The characteristics of the proposed protocol and its features are presented, and a simulator is built to examine its performance. The performance of the protocol is compared with that of the virtual-time carrier sense multiple-access (VT-CSMA) protocol. The results show that, although the proposed protocol has less throughput than the VT-CSMA protocol, its behavior is better than that of VT-CSMA with respect to high-priority packets. This behavior is the main goal of the protocol, which reduces high-priority-packet loss
