“…In the world of convergent multimedia communications and Next Generation Networks, satellite systems play an important role as access networks [1][2][3] due to their capability of providing global coverage, and recent research works [4][5][6] are pushing further the limits of this technology. However, the modern end user wants to access multimedia, real-time, and interactive services, demanding increasing amounts of bandwidth, through satellite systems, and with strong quality-of-service (QoS) requirements [7].…”

Satellite is often used as an access network in the Next Generation Networks landscape, where multimedia and real-time services are supported by return channels. However, these satellite return channels are a very limited resource with many terminal stations competing for its use, making its efficient assignation one of the key problems to solve in order to increase network performance. This article presents an innovative implementation of the resource allocation mechanism demand assigned multiple access (DAMA) applied to satellite return channel assignment, which provides support for dynamic allocation and quality-of-service. This resource allocation mechanism has been validated with the special purpose advanced Internet network emulator, using the test lab implementation to optimize traffic mapping and queue parameters directly in the field. The numerical results for the different test cases considered are presented, showing that the DAMA algorithm provided is an efficient way of assigning resources, and also helping in the comparison of the different capacity request mechanisms described in the standard.

“…An integration of the mobile satellite and terrestrial satellite-based wireless & mobile communications 4G is particularly important for global providing of the mobile broadband access to Internet, many m-Applications, multimedia VoIP, and other telecom services for geographically dispersed mass users in support of anytime, anywhere, and any required quality of service (QoS) capabilities in a low-cost way [1][2][3]. Thus, the convergence of hybrid satellite DVB-RCS broadcasting/multicasting systems side by side with terrestrial satellite-based broadband wireless 4G WiMAX becomes the most perspective networking technology for BRIC and other countries with many remote, rural, and difficult for access (RRD) sparsely populates territories [2][3][4].…”

The convergence of satellite DVB-S2/RCS broadcasting/multicasting systems side by side with terrestrial mobile satellite and broadband wireless 4G WiMAX becomes the most perspective networking technology for BRIC and other countries with many remote, rural, and difficult for access (RRD) territories. The RRD regions differ also by the poor terrestrial core infrastructures and sparsely populated areas. However, the recent broadband satellite systems are based mainly on centralized (i.e., star-like) low-meshed architecture. It requires providing a high concentration of the terrestrial traffics. Hence, such structures are not adequate to the characteristic RRD distributed traffic topology. Therefore the cost of these centralized systems is growing unacceptably for deployment of the 4G public broadband communications in RRD regions. This paper focuses on the developing and the performance analysis of the low-cost, fully distributed (i.e., gridlike) and mesh hybrid networking technology DVB-S2/RCSWiMAX which meets the RRD requirements.
