| 摘 要： | 针对定向发送与接收算法（DTRA）在网络节点密度较高、拓扑结构变化缓慢时，存在的邻节点发现不完全和邻节点频繁重复发现等问题，基于定向通信提出一种DTRA改进方案。理论分析结果表明，异步扫描帧的引入使该方案有效提高了邻节点发现概率和网络数据吞吐量。

| Abstract: | Aiming at the problems of Directional Transmit and Receive Algorithm(DTRA) such as neighbor discovery inadequacy and frequent neighbor rediscovery when the nodes density is high,or the topology of the network changes slowly,this paper puts forward an improved scheme of DTRA based on directional communication.Theoretical analysis results show this scheme can increase the probability of neighbor discovery and the data throughput of the network through the introduction of asynchrony scan frames. |
