Throughput Analysis and Frame Length Adaptive for AOS Packet Service

The AOS packet service organization is presented firstly in this paper. Based on it, the AOS packet service throughput is analyzed. Then the relations between the frame length of AOS space data link protocol sublayer, bit error rate (ber) of physical layer and the AOS throughput are discussed and the optimal frame length which gains the maximum throughput under a certain ber is obtained. Consequently, a frame length adaptive scheme is proposed to control the frame length for the maximum throughput according to the different channel state information (CSI). Simulation results show that compared with fixed length frame transmission, the proposed scheme can improve the AOS throughput performance availably.
