In this paper, the authors present a spatial reused bandwidth reservation scheme in Time Division Multiple Accesses (TDMA)-based uplink channel of satellite networks by using directional antennas. Directional antennas technology in wireless network provides the capability for considerable increase in spatial reuse, which can improve bandwidth utilization and satisfy the Quality of Service (QoS) requirement. A bandwidth reservation scheme based on max-min dynamic bandwidth allocation is discussed and implemented in ns-2. They have carried out simulations to study the performance of their scheme. The proposed scheme performs better in terms of QoS call success rate, throughput and delay. In future network scenario that including more QoS required traffic, it's more preferable.
