Directional antenna neighbor discovery method, device, electronic equipment and storage medium

Abstract

The present invention provides a directional antenna neighbor discovery method, device, electronic equipment and storage medium, which is applied to a cluster head node. The method includes: broadcasting an initial acquisition frame and a reference distribution frame in a target antenna sector; continuously switching beams to the target antenna Each member node within the sector sends an on-demand frame, and completes the handshake communication with each member node according to the reply frame sent by each member node; wherein, the reply frame is received by each member node on its respective determined receiving beam After the on-demand frame, it is sent to the cluster head node according to the reference distribution frame; the receiving beam is determined by each member node based on the initial capture frame. Therefore, in the scenario where the communication distance is long, the network coverage area is large, and the node distribution is sparse, the high gain advantage of the directional antenna can be used, and the problem of neighbor discovery difficulties caused by the directional antenna can be overcome, and the neighbor discovery can be quickly completed, improving Network construction efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device, electronic equipment and storage medium for directional antenna neighbor discovery. Background technique [0002] In the scenario where UAVs are applied, compared with the single-UAV working mode, the multi-UAV collaborative work system has the advantages of wider coverage and higher execution efficiency. It can exert unique advantages in areas such as traffic management and battlefield precision strikes. [0003] In order to allow the UAV cluster to better complete tasks through cooperation, the entire cluster can be formed into a mobile ad hoc network (MANET), which ensures that each node can complete its own tasks, and can complete the tasks between nodes while moving. information interaction. Each node in the mobile ad hoc network plans the overall behavior of the network through interactive information, which can effectively meet the ne...

Problems solved by technology

At the same time, when the UAV is flying, the fuselage will also affect the coverage of the antenna, and a group of omnidirectional antennas cannot cover the surrounding area of ​​the fuselage. The traditional mobile ad hoc network architecture based on omnidirectional antennas is not very good in these scenarios. In the case where omnidirectional antennas cannot be used, the traditional method of neighbor discovery based on omnidirectional antennas cannot meet the needs of network construction.
