%X The design of a routing protocol for the provision of QoS in a satellite network is a challenging task. This paper proposed a novel spatial reused bandwidth reservation for QoS guaranteed in satellite networks based on directional antennas. Many important applications, such as audio/video conferences and distance education, require the quality of service guarantee in satellite networks. Directional antennas technology in wireless network provided the capability for considerable increase in spatial reuse, which increased the efficiency of communication. It studied a time division multiple accessTDMA-based bandwidth reservation scheme by using directional antennas in satellite networks. This scheme allocated and reserved different time slots to different directional ground terminals, which could improve the spatial reuse of bandwidth resource and the efficiency of communication. This paper carried out simulations to study the performance of this scheme. The proposed scheme performs better in terms of QoS call success rate, throughput and delay.
