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 cacheenabled network are elaborated based on the traffic queue state. Moreover, we propose to exploit the packets cached at cacheenabled 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. Index Terms-Caching, dynamic traffic, interference cancellation, packet loss rate, Poisson point process.
Analytical modeling for traffic dynamics has been studied in REF to investigate packet loss rates for cache-enabled networks.
