Abstract: The integrated network of air, space, sea, and land is a complex system that connects and integrates different networks and nodes. It is characterized by being distributed, heterogeneous, time-varying, and self-organizing. The study of this network has become a hot topic among scholars due to the widespread application of technologies such as 5G, artificial intelligence, Internet of Things, and edge computing. By using parallel intelligence, researchers can model and generate data that overcomes the challenge of data and scenario scarcity. The air-sky-sea-ground integrated observation methods are used to identify, investigate, and rescue suspicious areas following accidents during maritime search and rescue, which has both practical and theoretical significance. The effectiveness of the proposed model is verified by computational experiments based on air-sky-sea-ground integrated four-dimensional network.
