为多跳分布式无线网络提出了一套灵活而有效的自适应获取冲突避免 (AACA)的多址接入协议 .它综合了多信道和随机附带预约的思想 ,有效地解决了多跳网络环境下出现的隐藏终端和暴露终端问题以及由于节点的移动而造成的侵入终端问题 .在该协议中 ,各节点自适应预约所要使用的空闲业务信道 ,预约之后的通信过程不会受到其它节点的干扰 .AACA协议有三种形式 ,即AACA SDT/MDT/RDT协议 ,它们使用任意确定数目的信道 ,在总带宽相同的情况下表现出比单信道RTS/CTS协议更好的网络性能
A flexible and effective multiple access protocol for adaptive collision avoidance avoidance (AACA) is proposed for multi-hop distributed wireless networks.It combines the idea of multi-channel and random attachments, and effectively solves the problem of multi-hop network environment Hidden terminals and exposed terminals, and intrusion terminal problems due to node movement, in which each node adaptively reserves idle traffic channels to be used and the communication process after reservation is not interfered with by other nodes The AACA protocol comes in three forms, the AACA SDT / MDT / RDT protocol, which uses any given number of channels and shows better network performance than the single channel RTS / CTS protocol at the same total bandwidth
