摘要
该文提出了一种基于MAC层协议的CSMA-DAMA实时调度算法,可以更好地支持多媒体业务的实时传 输。对此调度算法的性能进行了理论和仿真分析。在分析中采用了能更好地反映多媒体业务特性的自相似模型,使 性能的评价更加准确。通过引入按需分配机制和漏桶算法,使其在实时数据传输性能的各个方面均得到有效提高, 可以更好地满足多媒体业务的实时性要求。
A new scheduler algorithm CSMA-DAMA based on the Media Access Control (MAC) sublayer is proposed, which could provide a better service for the multimedia real-time transmission. Theoretical and simulation analyses of the performance are given in which the self-similar model are used to characterize the multimedia traffic better and make the evaluation more precisel. This algorithm obtains a great improvement in the performance of the real-time data transmission and satisfies the real-time requirement of the multi-media traffic better by introducing the assignment on demand and leaky bucket algorithm.
