| Abstract: | 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. |
