摘要
定向天线在空间上指向传输期望的通信区域,在通信容量和信息安全方面具有技术优势。设计了定向天线的方向图模型和邻居发现过程算法,针对相邻节点之间的通信距离与旁瓣-旁瓣通信距离、主瓣-旁瓣通信距离的相对关系,分析了定向天线组网的邻居发现过程;基于Qualnet网络仿真平台,仿真分析基于纯定向窄波束天线的数据链邻居发现、链路建立和路由算法,验证了邻居发现过程的正确性。
The directional antenna,which spatially directs towards the desired communication area,has a technical advantage in terms of communication capacity and information security.The direciton map model and the neighbor discovery process algorithm of directional antenna are proposed.Aiming at the communication distance relationship between adjacent nodes and side lobe– side lobe,main lobe– side lobe,the neighbor discovery process analysis of directional antenna is completed.Simulation analysis of nieghbor discovery,link establishment and routing algorithm for pure directional beam antenna’s data link is completed based on QualNet,and it also veryfies the correctness of neighbor discovery process.
