Paper Abstract

The traditional bandwidth allocation schemes are based on layered design. They solve the problem at Medium Access Control (MAC) layer only and do not consider the variable channel state and Quality of Service (QoS) of traffic flows which will influence the performance of bandwidth allocation scheme seriously. This paper proposes a cross-layer bandwidth allocation scheme for the broadband satellite network which supports the transmission of voice traffic and Internet data. This scheme combines the QoS of traffic flows at application layer and the channel state of the physical layer with the bandwidth allocation scheme in a cross-layer optimization. The master station computes a cost function that considers all the relevant parameters and gets the most efficient bandwidth assignments through dynamic programming algorithm. Numerical results show that the proposed scheme can adapt to variable channel state and increase the goodput of Internet data as much as possible without deteriorating the QoS of voice traffic.
