在使用随机几何工具对启用缓存的网络进行分析时，我们没有假设完全加载的单元，而是在这封信中重点关注动态流量。通过对请求到达和离开的流量动态进行建模，基于流量队列状态详细阐述了大规模缓存网络中满负载、空闲负载和中等负载单元的概率。此外，我们建议利用启用缓存的用户缓存的数据包作为辅助信息来消除传入干扰。然后，研究启用缓存和不启用缓存的用户的丢包率。仿真结果验证了我们的分析。
Instead of assuming fully loaded cells in the analysis on cache-enabled networks with tools of stochastic geometry, we focus on the dynamic traffic in this letter. With modeling traffic dynamics of request arrivals and departures, probabilities of full-, free-, and modest-load cells in the large-scale cache-enabled network are elaborated based on the traffic queue state. Moreover, we propose to exploit the packets cached at cache-enabled users as side information to cancel the incoming interference. Then, the packet loss rates for both the cache-enabled and cache-untenable users are investigated. The simulation results verify our analysis.
