The application claims a dynamic cooperative perception content deployment optimization method, belonging to the field of mobile edge network storage and content distribution, specifically comprising: an edge server collects historical traffic data of short video content, uses a GARCH model to extract volatility rate characteristics of the sequence, and inputs the same into a dynamic LSTM model with a fusion attention mechanism together with historical data to accurately predict content popularity at the next moment. On this basis, an edge controller monitors network link status in real time, dynamically calculates a cooperative radius based on network load to determine a cooperation range; then, combined with predicted popularity, neighbor node cache status and access time delay, the cooperative gain of content is calculated, and a hierarchical cooperative deployment strategy is used to store content decisions in local nodes or overflow to neighbor nodes within the cooperative radius. The application reduces service time delay in network congestion and traffic mutation scenarios, and realizes virtual expansion of edge storage capacity and improvement of cache hit rate through a neighbor cooperation mechanism.
