An adaptive MAC protocol for satellite ATM

We analyze the medium access control (MAC) protocols for satellite ATM, which use an adaptive random-reservation scheme to request the transmission slots and transfer different classes of data by taking the advantage of on-board radio resource management to provide the qualities of service. In addition, our MAC protocol design is based on multiple-frequency time division multiple access (MF-TDMA), which can save the uplink transmission power and occupy almost full time slot to achieve the high throughput. In this paper, OPNET Modeler/Radio is used to simulate the specific contention and reservation algorithm of MAC protocols.
