Abstract

This paper proposes a new MAC propocol for high-speed MAN. The proposed protocol is based on the P$_1$-persistent tranmission scheme and each node calculates the transmission probability periodically by using delay information(DI). A window mechanism for the calculation of message delay in each node is proposed to improve the adaptability of the proposed protocol to traffic changes. The capactiy of the proposed protocol is analyzed. The simulation results show that the proposed protocol gives fair message delay under heavy load conditions and, when the transmission speed or distance is increased, the message delay variation of the proposed protocol is less than that of IEEE 802.6 DQDB.
