混合自由/按需分配多址接入协议(CFDAMA)将按需分配方式和自由分配方式相结合,可以确保资源分配的合理性和公平性。在总结现有CFDAMA协议的基础上,以提高网络吞吐量,降低平均时延为目标,提出了一种CFDAMA改进协议,采用基于最大Lyapunov指数的信源预测模型对用户在下一时刻发送队列中即将到来的突发数据分组进行预测,使用户在发送时隙请求到获得时隙分配之间的数据分组能够及时的发送出去,减小平均端到端时延。
Hybrid Free / On Demand Assigned Multiple Access Protocol (CFDAMA) Combining on-demand and free-allocation modes ensures that resource allocation is justified and fair. On the basis of summarizing the existing CFDAMA protocol, this paper proposes a CFDAMA protocol to improve the network throughput and reduce the average delay. The source prediction model based on the maximum Lyapunov exponent The incoming burst data packets are predicted so that the data packets sent by the user during the time slot request to the time slot assignment can be sent out in time to reduce the average end-to-end delay.
