Abstract

The invention discloses an ad hoc network clustering method of a multi-directional antenna. The ad hoc network clustering method comprises the following steps of: performing acute initialization on multi-unmanned-platform networking, and binding key information for each node after the nodes of the multi-unmanned-platform networking are started; judging whether existing network information is monitored or not by each node according to the respective key information; if so, transmitting network access request information to apply for access; if not, upgrading the node to a cluster head node, andbroadcasting a network access invitation information frame; judging to access the network by the cluster head node; performing network service maintenance, namely, entering a service process after networking of each node is completed; at the end of each communication period, adaptively updating the cluster head node in the cluster and adding a backup cluster head node; and at the end of each communication period, enabling the cluster head node to interact with each node in the cluster in sequence to finish time calibration and position calibration, and maintaining the network to enter the next communication period. According to the ad hoc network clustering method, the network utilization rate of an ad hoc network is improved while the continuous availability of the link is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an ad hoc network clustering method with multiple directional antennas. Background technique [0002] Self-organizing network technology is widely used in multi-unmanned platform networking fields such as inter-satellite networking, bullet-to-bullet networking, unmanned ship-to-ship networking, and UAV-to-UAV networking in a wireless environment. Traditionally, multi-unmanned platform networking generally uses omnidirectional antennas for point-to-point business transmission, which will bring two risks: one is that the location information in the combat environment is easy to be discovered by the enemy, and there is potential danger; the other is , causing communication interference to other surrounding unmanned platforms. Since the directional antenna can point to the desired unmanned platform in space, it has technical advantages in ensuring information security...
