A BE Services Bandwidth Request Scheme Based On Collision Waiting
Hong Ni · Microcomputer applications · 2010
The bi-directional terrestrial multimedia broadcast system needs to support the interactive broadcast,data and voice service,and to supply users with QoS assurance.A BE services bandwidth request scheme based on collision waiting was proposed to meet the need of bi-directional terrestrial multimedia broadcast system.The proposed scheme can automatically accommodate itself to the network bandwidth request load,the number of transmission opportunity per frame and the times of sending attempt of the current bandwidth request.The simulation results show that the proposed scheme can maintain higher utilization of bandwidth request transmission opportunity and lower drop probability of bandwidth request,compared to the traditional Truncated Binary Exponential Backoff scheme.
