摘要
本文讨论了MC-CDMA多媒体数据规划协议,多媒体数据按BER指标分类,根据各类数据BER要求,采用蚂蚁算法对用户分组数据进行规划。对照传统的“先到先服务”(FCFS)方法,进行了仿真分析,结果表明平均吞吐率、平均时延及平均丢包率均有改善。
In this paper, a medium access control (MAC) protocol with BER scheduling is proposed in MC-CDMA. The scheduler based on ants colony algorithm determines a good accommodation according to BER requirements in the slots of a frame. The performance is evaluated by using average throughput, average delay and average loss rate compared to the conventional “First Come First Serve” (FCFS) principle. Simulation results demonstrate the advantages of the proposed algorithm.
