Research of MAC protocol in near space communication network
YU Jiang-ming · Computer Engineering and Applications Journal · 2011
The near space network has become the research focus on rapid developing of space network.Near space communication network demands higher real time and effective transmitting messagea,proper medium access control protocol is designed.Based on Demand Assignment Multiple Access(DAMA) protocol,combined with free assignment,Combined Free Demand Assignment Multiple Access(CFDAMA) protocol is applied to near space communication network,OPNET simulation model is created.Simulation results show that not only CFDAMA protocol can reduce mean end-to-end network delay,guarantee the real time of message,but also promote the throughput of network.
