Cross-layer design for call admission control of a high-capacity GEO satellite network with on-board cross-connect

摘要

This paper addresses cross-layer design of end-to-end call admission control and beam-to-beam connectivity provisioning for a high-capacity multi-beam GEO satellite network with on-board cross-connectivity. On-board satellite switching is a technology designed to offer heterogeneous services, especially in demographically dispersed areas. Nevertheless, full on-board switching techniques are far from maturity. Their implementations have been proven expensive and difficult. There are also high risks involved in launching satellites for the stationary orbit surrounding the Earth. As a substitute, a satellite network with on-board cross-connect is devised in this paper. Connectivity provisioning and call admission control mechanisms associated with such a network are also presented. Simulation studies are conducted to show the effectiveness of the proposed mechanisms.
