“…Similarly in the spirit of Reference [14], selection of the most appropriate satellite depends on the geographical location of terminals and the handover occurrence time. In Reference [15], the performance of this geographical location-based satellite selection scheme was evaluated and compared to that of the widely used baseline satellite selection scheme. The latter simply selects the satellite with the highest elevation angle during the initial set-up of connections or upon a handover occurrence [16].…”

“…Indeed, if a user request comes in between staggered start times of two adjacent multicast channels, the user joins to the most recently started multicast session and then requests the missing part from a nearby neighbour instead of receiving it from a patching unicast channel at a local server. Savings in these unicast channels will be exploited to satisfy requests coming from mobile nodes roaming within the coverage area of the satellite system [19]. To allow users to receive their VoD applications with higher degree of mobility and to guarantee a smooth streaming of video data, handoff-related schemes, such as that proposed in Reference [20], can be considered as well in the implementation of the architecture.…”

SUMMARYTo meet an ever-growing demand for wideband multimedia services and electronic connectivity across the world, development of ubiquitous broadband multimedia systems is gaining a tremendous interest at both commercial and academic levels. Satellite networks will play an indispensable role in the deployment of such systems. A significant number of satellite communication constellations have been thus proposed using Geostationary (GEO), Medium Earth Orbit (MEO), or Low Earth Orbit (LEO) satellites. These constellations, however, either require a potential number of satellites or are unable to provide data transmission with high elevation angles. This paper proposes a new satellite constellation composed of Quasi-GeoStationary Orbit (Quasi-GSO) satellites. The main advantage of the constellation is in its ability to provide global coverage with a significantly small number of satellites while, at the same time, maintaining high elevation angles. Based on a combination of this Quasi-GSO satellites constellation and terrestrial networks, the paper proposes also an architecture for building a global, large-scale, and efficient Video-on-Demand (VoD) system. The entire architecture is referred to as a 'Theatre in the Sky'.

“…Today, the research of location technology is one of the great issues in area of multimedia, networks, etc as required wide-band services. They propose a geographical location service based satellite selection scheme which is providing global coverage with a significantly small number and high elevation angles [20]. For the location information Nancy and Ahmed presented a novel framework for user mobility prediction using trajectory and destination with knowledge of user's preferences, goals, and analyzed spatial information [17].…”

The support of IP-based real-time multimedia services using voice and video in the next generation network system have been proposed and deployed in the past. However, many of them still lack deployment and need improvement their research for applying ubiquitous environment. In this paper, we have developed an intelligent multimedia convergence service, especially include voice and video over internet protocol service based on session initiation protocol (SIP) which are capable of dealing with polymorphic functional changes based on the interpreted user requests through multi-modal interactions. We presents SIP infrastructures with effective multimedia convergence service result and objective MOS method for quality of service (QoS). Finally, our performance research of multimedia convergence service for ubiquitous environment is tested using our dynamic multifunctional systems with location-based method which also use our session initiation protocol infrastructures and shown the result with 3D virtual monitoring for physical action including QoS measurement of voice and video over IP.
