21289 针对水声通信网络邻节点发现困难的问题，该文提出一种基于定向收发的邻节点发现机制。 Considering the difficulty of neighbor discovery in underwater acoustic communication networks, aneighbor discovery mechanism is presented based on directional transmission and reception.
21290 该机制中节点只采用定向方式发送和接收信号，能够避免增益不对称引起的隐藏终端问题，增加网络覆盖范围； In this mechanism, the nodes only send and receive signals directionally, which can avoid the hidden terminal problem caused by asymmetric gain and increase the network coverage.
21291 时间被划分为邻节点发现时隙和侦听回复时隙，发现时隙中节点发送HELLO信号，然后接收邻节点回复的REPLY信号， Time is divided into neighbor discovery time slot andlistening & reply time slot. In neighbor discovery time slot, the node sends the HELLO signal, and then waitsto receive the REPLY signal sent by its neighbor node.
21292 侦听回复时隙中节点侦听源节点发送的HELLO信号，然后回复REPLY信号， In listening & reply time slot, the node listens the channel for the HELLO signal sent by the source node, then replies REPLY signal to the source node.
21293 节点通过基于竞争的HELLO/REPLY两路握手以直接发现和间接发现两种方式完成邻节点发现，能够克服“聋”节点问题，提升邻节点发现效率。 The node can discover its neighbor through HELLO/REPLY two-way handshake based on competition and direct &indirect discovery, which can overcome the “deaf” nodes problem and improve the efficiency of neighbor discovery.
