Paper Abstract

The Bandwidth request algorithm which intervenes in the bandwidth-on-demand (BoD) access mechanism plays an important role in DVB-RCS satellite systems to optimize bandwidth utilization. In this paper, a memory cost improved bandwidth request algorithm (MCI-BRA) is proposed. The MCI-BRA deals mainly with the memory cost which is measured as the queue size at the terminal while offers a controllable trade-off between delay and efficiency. A traffic plane model for a satellite system using DVB-RCS is also described. Several assumptions are discussed, followed by detailed description of the MCI-BRA. Comparisons between the proposed algorithm and existing ones are also presented and analyzed. The simulating results show that MCI-BRA proposed in this work performs better than existing algorithms on controlling memory cost while handles the delay and efficiency issues as well as the existing ones.
