Neighbor discovery method of directed ad hoc network

Abstract

The invention relates to a neighbor discovery method for a directional self-organizing network, and belongs to the technical field of directional self-organizing networks. According to the method, the UCB strategy is used for selecting the action, so that the node performs appropriate exploration, and the situation that the node is caught in a suboptimal strategy or the neighbor discovery process is not converged is avoided. Rewards obtained by the nodes are related to whether the nodes observe collision or not, namely, the influence of current time slot neighbor discovery results on later time slot neighbor discovery is considered, the neighbor discovery process is accelerated, and neighbor discovery delay is reduced. According to the method, an iterative estimation value function is utilized, an environment model of a directional self-organizing network does not need to be known, meanwhile, a Q-Learning learning algorithm is independently used for nodes in the network to achieve self-adaptive neighbor discovery, the nodes do not interfere with one another, decision is made independently, and the neighbor discovery problem is simplified.

Description

technical field [0001] The invention relates to a neighbor discovery method of a directional self-organizing network, which is used for the process of self-adaptive discovery of neighbor nodes by a node in the directional self-organizing network, and belongs to the technical field of the directional self-organizing network. Background technique [0002] In directional ad hoc networks, since the energy of directional antennas is concentrated in one direction, there is less interference to other directions. Using directional antennas can improve the spatial multiplexing rate, but at the same time increases the difficulty of neighbor discovery. Two neighboring nodes equipped with directional antennas need to meet two conditions to discover each other: one is that the beams of the directional antennas must be aligned with each other, and the other is that one of the nodes is in the transmitting mode and the other node is in the receiving mode. Due to the narrow beam width of the...
