摘　　要：近年来,临近空间通信网络开始成为新的研究热点,但对临近空间通信网多址接入协议(MAC协议)的研究较少,且已发表的论文仅关注固定终端。为适应移动终端快速接入网络的需要,文章提出将基于竞争机制的ALOHA协议应用到临近空间通信网中,并利用OPNET网络仿真软件对其性能进行分析。仿真结果发现,ALOHA协议可以很好地应用于网络负载较小的临近空间通信网。The near space communication network is becoming of research focus for recent years.However,fewer researchers who are interested in MAC protocol only focus on fixed terminals.In order to adapt the needs of dynamic network,ALOHA protocol which is based on compete mechanism is applied to near space communication network.And a simulation is also established using OPNET software.Simulation results show ALOHA can be used effectively in the near space communication network in the case of less traffic.
