Fair Access

To support a great number of dispersed users in a wider area with high-speed communication services, we investigate a highly efficient medium access control (MAC) scheme for the hierarchical ring networks. In these networks, traffic congestion may happen due to the mismatch of transmission speed between backbone and outer rings. To cope with the issue, we propose a refined MAC protocol based on the cyclic reservation-based access control method for different network resources, viz. network bandwidth and buffers. By this approach, our protocol can achieve fair access to the network resources and avoid traffic congestion at the same time. Also, the networks will have the properties of extremely high throughput, low delay, fair access, simple implementation, and so forth. To evaluate the network, several simulative experiments are performed and some optimistic results are revealed.
