The space-based network is made up of aircrafts, spacecrafts, and all kinds of satellites in different orbits, which is hierarchical and tridimensional. In this special hierarchical network, a suitable multiple access protocol is required if the satellites with high velocity sharing the limited channel resources reasonably. There are majority kinds of services and traffic required during the disaster or emergent times. Thus, a novel hybrid access protocol based on traffic priority in the space-based network is proposed, where the frequency-time division multiple access (F-TDMA) is introduced into the space-based network first, and some improvements by jointing the time-domain of F-TDMA to meet the specific requirements of the satellite users are in this paper. Moreover, different traffics in the space-based network are considered as well. The analysis and simulation results show that the hybrid access protocol can obtain a higher throughput and a lower collision probability with a lower average delay comparing with the traditional collision avoidance carrier sense multiple access (CSMA/CA). |
