| 摘 要： | 为充分利用定向天线的引入而带来的技术上的优势,提出了一种基于定向天线的自组网邻节点发现算法。通过空闲节点定向快扫描侦听信道,发送节点在相同方向上发送6次HELLO信息来减少隐藏终端问题,同时引入节点信息共享机制。仿真结果表明,该发现算法具有发现速度快,对节点密度有较好的适应性等特点。

| Abstract: | A new adjacent node finding algorithm based on directional antennas in ad hoc networks is proposed to make full use of the advantage of directional antennas.The idle nodes monitor the channel with rapid scanning.The sender sends the HELLO information in the same direction for six times to hid the terminal perfectly.At the same time,the mechanism of sharing node information is introduced into the algorithm.The simulation result indicates that the new finding algorithm has the characteristics of rapid finding... |
