本文讨论了分组预约多址接入（ＰＲＭＡ）协议的缺点，提出了一种冲突消弱分组预约多址接入（ＣＲＰＲＭＡ）协议，理论分析和计算机仿真均表明ＣＲＰＲＭＡ的性能优于ＰＲＭＡ． This paper discusses the shortcomings of the packet reservation multiple access (PRMA) protocol and proposes a collided weak packet-based reservation multiple access (CR-PRMA) protocol. The theoretical analysis and computer simulation show that the performance of CRPRMA is better than PRMA.
