摘要

针对空天地一体化网络中恶劣的自然条件可能造成连通异常和通信阻塞的情况，对一种新的空天地一体化网络缓存方法进行研究，即基于聚类的内容缓存方法。基于空天地一体化网络架构，利用提取的内容特征来预测流行度，并用于缓存替换决策。内容的流行度预测是由动态聚类算法实现的，这种方法可以有效地减轻地面核心网的通信压力，从而进一步提升用户体验。使用开放数据集对算法进行评估，实验仿真结果证明了该方法的可行性和有效性。

Abstract

This paper proposed a new space-air-ground integrated network caching method

that was

cluster based content caching method.Based on the space-air-ground integrated network architecture

this method used the extracted content features to predict the popularity and used it for cache replacement decision.Content popularity prediction was realized based on dynamic clustering algorithm.This method could effectively reduce the pressure on the ground backbone network and further improve the quality of user experience.It evaluated the performance of our method using the open Douban movie review dataset.This dataset could be used to simulate user requests.Experimental simulation results showed the feasibility and effectiveness of the method.
