Bandwidth and Storage Efficient Caching Based on Dynamic Programming and Reinforcement Learning

Proactive caching holds the promise of coping with the explosively increasing traffic demands of next generation mobile networks. However, it may also incur extra pushing and storage costs for base stations (BSs). By taking these costs into account, we are interested in maximizing the average profit for the BS. A joint pushing and caching (JPC) approach is investigated to determine whether and when to push and how long a file should be cached at...
