“…DVB-S2 is used on the forward link whereas DVB-RCS is used on return link transmission. DVB-S2 is used because it supports Adaptive Coding and Modulation (ACM) and adapts per-time slot basis depending on the Signal-to-Noise-plus-Interference Ration (SNIR) at the destination terminal whereas on the return link, MF-TDMA and adaptive coding is used to enable bidimentional framing [12].

The demand for anytime-anywhere connectivity has accelerated the emergence of new technologies and integrated networks for better quality of service (QoS). With the introduction of IEEE802.16, mobility in broadband services has become reality. Whilst broadband services in urban area are common, it is deemed luxury service in rural and remote area. Since satellite network provides wider geographical coverage, a hybrid network between satellite and IEEE 802.16 will be the key to affordable broadband connectivity to rural and remote area. In this paper, a header compression scheme is proposed over hybrid satellite-WiMAX network. The proposed header compression scheme (Hybrid-ROHC) will enable the saving of resources over the hybrid network where bandwidth is a premium.

“…The integration of WiMAX, which is another next generation technology, with the satellite networks has attracted the interest of some research communities recently. In 9, Castro et al have studied the cross‐layer optimization of real‐time traffic (specifically VoIP) transmission over hybrid networks entailing DVB‐RCS/S2 satellite (Ka band, GEO) and WiMAX. The optimization has focused on reducing the total transmission delay and jitter.…”

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.
