Th is paper presents a nove lmed ia access contro l (MAC ) pro toco l designed for, but no t lim ited to , use in geostationary ( GEO ) broadband commun icat ion satellites using ATM technology w ith composite traffic load. Besides using variab le-ra te DAMA for rt /nr-tVBR traffic, a strategy o f random transm ittingw ith piggybacking reserva tion request forUBR traffic is used. OPNETTM M odeler simulation show s that the considerab le improvements in delay and throughpu t performance are ach ieved if the nex-t generation satellite techno logy ( OBP) and the adaptiveMAC are emp loyed.
