【摘要】：波束成形天线相比较定向天线具有波束集中,抗干扰能力强等特点,配备波束成形天线的节点间通信复杂,造成网络同步困难。文中提出一种分簇网络时间算法解决基于波束成形天线网络同步问题,算法分为选举,分簇,同步三个阶段,选举阶段选举网络根节点,分簇阶段工作于定向天线且网络时间异步场景下,利用网络根节点作为分簇的初始节点完成网络分簇,同步阶段利用簇间同步与簇内迭代完成全网节点同步。仿真分析了算法的开销并能够促使网络时间收敛。
[Abstract]:Compared with directional antenna, beamforming antenna has the characteristics of beam concentration, strong anti-jamming ability and so on. The communication between nodes equipped with beamforming antenna is complex. In this paper, a clustering network time algorithm is proposed to solve the synchronization problem based on beamforming antenna network. The algorithm is divided into three stages: election, clustering, synchronization, and electing the root nodes of the network. The clustering phase works in the directional antenna and network time asynchronous scene. The root node of the network is used as the initial node of the cluster to complete the network clustering. Synchronization between clusters and intra-cluster iteration is used to synchronize the nodes in the whole network, and the overhead of the algorithm is analyzed and the network time converges.
