The invention discloses a low-delay unmanned aerial vehicle network handover method based on resource reservation. The method mainly solves the problems that in the prior art, deployment cost of a base station is high, handover delay is large, and resource allocation conflicts exist. According to the implementation scheme, unmanned aerial vehicle flight areas are clustered according to geographical grids; the node reports flight information to the cluster head according to the pre-switching information and the position information; the cluster head node generates inter-cluster interaction information according to the received flight information and sends the inter-cluster interaction information to each adjacent cluster; the cluster head nodes of the adjacent clusters release redundant reserved resources according to the inter-cluster interaction information, reserve time slot resources for the pre-switching nodes, update the inter-cluster interaction information and send the inter-cluster interaction information to the adjacent clusters; the pre-switching node monitors inter-cluster interaction information and stores reserved resource information related to the node; and after the handover of the pre-handover node occurs, the pre-handover node immediately works in the new cluster by using the reserved resource to complete the handover. The method is small in handover time delay, does not need the participation of a base station, is low in deployment cost, is free of conflicts in resource allocation, and can be used for an unmanned aerial vehicle self-organizing network in which nodes rapidly move.
本发明公开了一种基于资源预留的低时延无人机网络越区切换方法,主要解决现有技术中基站的部署成本高,越区切换时延大与资源分配冲突的问题。其实现方案是:将无人机飞行区域按照地理栅格分簇;节点根据预切换信息与位置信息向簇首上报飞行信息;簇首节点根据收到的飞行信息生成簇间交互信息并发至各邻簇;邻簇的簇首节点根据簇间交互信息释放冗余预留资源,为预切换节点预留时隙资源,更新簇间交互信息并发至各邻簇;预切换节点侦听到簇间交互信息,存储与本节点相关的预留资源信息;预切换节点发生越区切换后,立即使用预留资源在新簇内工作,完成越区切换。本发明的越区切换时延小,无需基站参与,部署成本低且资源分配无冲突,可用于节点快速移动的无人机自组织网络。
