Description

Technical Field

[0001] The present application belongs to the field of wireless communication network technology, and in particular relates to a wireless network quality assessment method and device based on active and passive collaborative measurement. Background Art

[0002] Intelligent agents, including drones, unmanned ground vehicles, unmanned boats, and unmanned underwater vehicles, are the product of artificial intelligence, robotics, and real-time control and decision-making systems. They are flexible, efficient, reliable, and highly adaptable. By designing intelligent perception, interaction, collaboration, and control methods for multi-agent systems, they develop strong autonomy and self-governance, enabling them to independently complete diverse tasks in complex environments.

[0003] Wireless communication networks are the foundation of communication and networking among intelligent agents. They transmit information over the air using electromagnetic waves, providing flexible, efficient, and reliable connectivity for intelligent agents. Wireless network edge devices, or communication relays, provide network access for intelligent agents, enabling them to communicate with other intelligent agents or computers. These include wireless base stations, wireless gateways, wireless routers, communication satellites, aircraft with communication relay capabilities, ground stations, ships, intelligent agents, and other wireless communication network platforms and devices that perform functions such as sending, receiving, forwarding, routing, and signal relaying network messages within wireless networks.

[0004] However, due to the open nature of wireless channel space, electromagnetic waves experience significant fading and interference when propagating through the air. When communicating with agents, wireless signal fading includes not only large-scale signal strength fading over long distances, but also slow fading due to path loss and shadow fading caused by obstructions. Furthermore, multipath propagation, where wireless signals travel along multiple paths through reflection, scattering, and diffraction, can also occur. In particular, different propagation paths have different propagation distances, arrival times, and phases, resulting in dramatic signal variations. The scattering environment of multipath propagation, combined with the mobility of agents, also causes dispersion in the wireless channel in time, frequency, and angle. Different agents and wireless devices can also interfere with each other during communication. This interference includes interference from signals transmitted by other communicating devices on an agent's receiver, interference between links when the same agent's transmitter simultaneously transmits signals to different receivers, interference from the same agent's transmitter on its own receiver when the agent simultaneously transmits and receives signals (self-interference), and background noise (white noise) outside the agent's communication band. To adapt to electromagnetic wave fading and interference, wireless communications employ different network protocols for different scenarios. These wireless communication-based network protocols differ significantly from those based on wired communications. While modern wireless communications widely utilize various multiplexing and multiple access technologies, beamforming and smart antenna technologies, spread spectrum and frequency hopping technologies, coding and modulation technologies, and spectrum resource allocation technologies to enhance network capacity, bandwidth, coverage, and reliability, their varying channel contention rules, data transmission methods, and packet loss and retransmission mechanisms significantly impact the network layer, resulting in varying characteristic distributions and jitter in round-trip delay and packet loss rate.

[0005] Fading and interference in wireless communications, as well as the impact of different wireless network protocols on network transmission, pose real challenges to agent-oriented mobile edge computing. To address this challenge, an agile and reliable assessment method is needed at the edge of wireless networks and communication relay carriers to enhance the agent's perception of the wireless communication network environment.
