Abstract

The invention discloses an intelligent neighbor discovery method and device for a directional antenna self-organizing network, and the method comprises the steps: constructing a reinforcement learning model through employing a receiving and transmitting mode and a scanning mode of a directional antenna; according to a Q value table in the reinforcement learning model, adopting an belonging-greedy algorithm to select a transmitting-receiving mode and a scanning direction of a node in the directional antenna self-organizing network; sending or intercepting a handshake packet according to the transceiving mode of the node, and carrying out three-step handshake interaction based on the handshake packet; detecting the conflict of handshake packets in the interaction process through the nodes, and determining a reward value in the reinforcement learning model according to conflict information and a receiving and transmitting mode; and updating a Q value table in the reinforcement learning model according to the reward value and a preset learning algorithm. According to the embodiment of the invention, the scanning strategy of the antenna is continuously adjusted through a learning mode, the conflict in the scanning process can be adaptively avoided, the link discovery can be accelerated when no conflict occurs in the handshake process, and the method is a fast and efficient neighbor discovery method in a directional antenna self-organizing network. Good application prospects are realized.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a method and device for finding intelligent neighbors in a directional antenna ad hoc network. Background technique [0002] The mobile ad hoc network based on directional antenna has many unique advantages compared with the omnidirectional antenna network. Firstly, the directional antenna can effectively improve the spatial multiplexing and improve the throughput of the network; secondly, the directional antenna can concentrate the energy in the main lobe beam, which can effectively improve the communication distance; in addition, the use of the directional antenna to send narrow beams for burst communication can effectively improve the resistance Jamming capability and concealment. [0003] The discovery of neighbor nodes is a key link in directional networking, and information can only be transmitted between nodes after mutual discovery is completed, and then...

Problems solved by technology

The traditional neighbor discovery algorithm is based on scanning. The node randomly selects the sending and receiving mode and scans according to the preset sequence. This method is very inefficient in large-scale and dense networks.
