Abstract

The past years have seen an explosion in the number of broadcasting network standards and a variety of multimedia services available to the mobile mass-market. Satellite communications has been gaining phenomenal growth and increasing interest over the last decade in its complementary but essential role for offering seamless broadband service coverage to potential users at every inch of the earth’s surface. However, mobile satellite network often feature unidirectional and long-latency, a great deal of research effort has been attempted for this bottleneck. Given the absence of feasible power control mechanism and reliable feedback information, the role of packet scheduling in such a network with large delay-bandwidth product is extremely challenging. In fact, an optimized media access control (MAC) layer protocol is essential for cost-efficient satellite networks to compete with other terrestrial modalities. In particular, the integration and convergence between satellite network and conventional terrestrial backbone infrastructure offers promising solutions for next generation service provisioning. In this chapter, the authors give a survey on the state-of-the-art on packet scheduling in hybrid satellite-terrestrial networks (HSTN). A whole range of issues, from standardization, system to representative scheduling methodologies as well as their performance trade-offs have been envisioned. Moreover, the authors investigate viable solutions for effectively utilizing the limited/delayed feedbacks in resource management functions. They examine the flexibility and scalability for the alternative schemes proposed in this context, and analyze the performance gain achievable on essential QoS metrics, channel utilization, as well as fairness.
