摘要
设计一种基于第三代短波链路自动建立(3G—ALE)技术的自适应多址接入算法。文中分析3G—ALE基本多址接入算法及改进型算渚的缺点,设计依据业务长、短不同而进行自适应接入的TA—CSMA算法,建立网络模型进行计算机仿真验证。仿真结果表明,TA—CSMA算法可以使网络呼损率及信道占用率明显降低,使网络吞吐量有较大提高。TA—CSMA算法是适合短波自组织网络的一种高效的多址接入协议。
An adaptive multiple access algorithms is designed based on high - frequency third, generation automatic link establishment (3G "ALE) technology. The basic algorithms of 3 G -ALE and shortcomings of the improved algorithms are analyzed, a traffic based on long and short different adaptive access to the TA - CSMA algorithm is designed, and the network model is established to carry on the computer simulation confirmation. Simulation results show that the TA - CSMA algorithm can effectively reduce the lost - call rate and channel occupation rate in the network, thus greatly improving the network throughput. The TA - CSMA algorithm is one kind of highly effective multiple access protocols suitable for high frequency self-organization network.
