The control frame tagged with the routing and state information can be sensed by the neighboring nodes. The ACK message sent by the upstream node is the RTS handshake with the downstream node, and the CTS/DATA/ACK exchange is set up.
在协议的控制帧中携带路由信息和状态信息,根据这些信息,判断存在的暴露终端和隐藏终端,同时利用上游节点的 ACK 应答作为与下游节点的 RTS 握手,建立 CTS/DATA/ACK的三次交互机制。
