“…Appropriate scheduling entitles the satelliteterrestrial cognitive networks with the ability to handle dynamic context-aware demands, reference [143] proposes a cooperative scheme by guarantee different bandwidth requirements of services. Packet scheduling schemes with service prioritization algorithm for multimedia delivery is proposed in [144], [145]. In [144], the proposed scheme is related to queuing state, link variations, and current QoS satisfactions.…”

The explosive growth of various services boosts the innovation and development in terrestrial communication systems for the implementation of the next generation mobile communication networks. However, simply utilizing limited resources in terrestrial communication networks is difficult to support the massive quality of service (QoS) aware requirements and it is hard to guarantee seamless coverage in far remote regions. Leveraging the intrinsic merits of high altitude and the ability of multicasting or broadcasting, satellite communication systems provide an opportunity for novel mobile communication networks with its tight interaction and complementary characteristics to traditional terrestrial networks. It is believed that the convergence of satellite and terrestrial networks can solve the problems existing in current mobile communication systems and make a profound effect on global information dissemination. In this paper, we make a comprehensive survey on the convergence of satellite and terrestrial networks. First, motivations and requirements of satellite-terrestrial network convergence are identified. Then, we summarize related architectures of existing literature, classify the taxonomy of researches on satellite-terrestrial networks, and present the performance evaluation works in different satellite-terrestrial networks. After that, the state-ofthe-art of standardization, projects and the key application areas of satellite-terrestrial networks are also reviewed. Finally, we conclude the survey by highlighting the open issues and future directions.

“…This in turn puts a great importance on the PS mechanism. Fan et al 6 examine the existing PS algorithms in SDMB and propose a cross‐layer scheme that is efficient in terms of average queuing delay, delay variation and channel utilization. The introduced packet scheduling scheme has two sub‐components: Cross‐Layer Delay Differentiation Queueing (CL‐DDQ) and Dynamic Rate Matching (DRM)‐based Dynamic Resource Allocation (DRA).…”

This paper describes and discusses a heterogeneous system of satellite and IEEE 802.16 WiMAX networks collaborating for the efficient delivery of multimedia services. We first elaborate on the rationale behind integrated satellite and WiMAX networks with an overview of current research on interworking of satellite and 3G/Beyond 3G terrestrial networks. Following this background, we propose a diverse set of enhancements and additions into WiMAX Base Station (BS) and Multicast Broadcast Service Controller (MBSC), which allows this interworking in the multimedia delivery context. We describe a WiMAX BS downlink scheduler that considers satellite channel conditions of the dual-mode SSs (Subscriber Station) while making resource allocation and packet scheduling. This scheduler interacts with another proposed module in MBSC, namely Satellite-Terrestrial Interaction Module, for performing these operations. Traffic for real-time multimedia and cache-based delivery is considered in the system. On the SS side, a lightweight signaling scheme between BS and SS for service continuity and control is presented.

“…In an informal test this is to first meet the demand of small users, dividing among all the possible resource remaining. A policy of fair share, of course, cannot be applied to connections with guaranteed service, where users pay to receive a certain level of service [50]. Let us suppose to have a resource with capacity C and n service users with applications for resource x 1 , ..., x n .…”
