This invention discloses a method and system for coordinating neighbor discovery conflicts in wireless ad hoc networks based on Q-learning. The method includes: constructing a wireless ad hoc network model and initializing its parameters; based on the initialized model parameters, determining the activation state of time slots according to the working sequence, running and updating relevant data, and determining whether to enter the next learning round based on the cumulative number of time slot activations; if entering the next learning round, calculating the average reward value and determining the node state for the next learning round, updating the Q-table, and selecting actions according to the ε-greedy policy to achieve neighbor information transmission and reception for nodes in the wireless ad hoc network model. This invention can effectively coordinate beacon conflicts and significantly improve the neighbor discovery efficiency of nodes. As a method and system for coordinating neighbor discovery conflicts in wireless ad hoc networks based on Q-learning, this invention can be widely applied in the field of communication technology.

The application discloses a kind of ultraviolet light communication cooperation networking method and system, comprising: all nodes in ultraviolet light network complete neighbor discovery, and establish neighbor table;The neighbor table only stores the distance information between nodes;According to the distance information stored in neighbor table, the distance from source node to destination node is obtained, and the time for transmitting each bit of data is dynamically adjusted according to the distance from source node to destination node;According to the distance information stored in neighbor table, the relay node in the shortest path from source node to destination node is selected;Data forwarding is carried out based on the adjusted time for transmitting each bit of data and the relay node in the shortest path;The application can effectively improve the throughput of network, and reduce the overall power consumption of network.

This application provides a node task execution method, apparatus, device, storage medium, and program product. The method includes: acquiring digital identity information and physical identity information of multiple nodes; the digital identity information is used to characterize the logical identity of the node in the communication domain, and the physical identity is used to characterize the entity characteristics of the node in the physical perception domain; performing consistency matching on the digital identity information and physical identity information of each node to obtain a matching result; determining a set of trusted candidate neighbor nodes based on the matching result; and executing a decision task based on the set of trusted candidate neighbor nodes. The solution of this application addresses the problem in the prior art where candidate forwarding nodes in UAV ad hoc networks are derived from ordinary neighbor discovery results, lacking verification of node identity trustworthiness.

This specification provides a message processing method, apparatus, electronic device, and medium. The method includes: receiving a first neighbor request (NS) message sent by a host, wherein the destination IP address in the first NS message is the host's IP address, and the source IP address in the first NS message is an all-zero address; if the destination IP address in the first NS message is a global unicast address, then sending a first neighbor advertisement (NA) message from each other interface except the interface that received the first NS message, wherein the source MAC address of the first NA message is the MAC address of that other interface, and the source IP address in the first NA message is the destination IP address in the first NS message; if no first NS message corresponding to the first NA message is received, then generating a neighbor discovery (ND) entry for the host based on the destination IP address and source MAC address of the first NS message.
