| 摘 要： | 对现有的周期预留多址接入(CRMA)协议进行了简化和改进，提出了简化的CRMA协议(S-CRMA)。S-CRMA协议对时隙结构进行了重新定义，取消了原有协议的REJECT、CONFIRM等命令，通过自适应地改变预留时隙的间隔，实现了网络在接入时延和接入速率方面的公平性。通过仿真数据和曲线，说明了基于S-CRMA协议的网络在平衡突发业务和非平衡突发业务两种条件下，均保证了各个本地节点的公平接入。

| Abstract: | In this paper, simplified cyclic reservation multiple access (S-CRMA) scheme is proposed and simulated. Slot structure of CRMA is modified and the commands, such as REJECT and CONFIRM, are abandoned in the S-CRMA protocol. With adaptive adjustment of slot reservation interval, fairness of local nodes is guaranteed in the aspects of access rate and access delay. Finally, S-CRMA protocol is simulated under balanced and unbalanced burst mode traffic. The simulation results illustrate the fair and efficient performance of S-CRMA protocol in the simulated local area network. |
