Abstract

In order to solve the problem of low channel utilization and throughput because of burstiness on high-priority service accessing the satellite channel on account of long-range combat aircraft transmitting different priority service when it accessed satellite channel, the paper proposed a dynamic channel access strategy supporting service with priority for satellite communication network. The access strategy constructed the spectrum pool to share channel through introducing the cognitive radio technology. It set the high-priority service accessing channel freely, meanwhile, it ensured low priority business access the channel successfully through reserving spare channel. When there was some service not accessing channel, the service used the queuing model for access. The simulation results show that this strategy can effectively guarantee the successful ratio of high-priority service accessing channel, meanwhile, it effectively reduces the access delay. When the access strategy is applied, it can effectively reduce the impact of burstiness on high-priority service accessing the satellite channel, which leads to improving the comprehensive utilization rate of the satellite channel, reducing the access delay of low-priority service and guaranteeing the throughput on low-priority service accessing the satellite network.
