Content caching for shared medium networks under heterogeneous users’ behaviors

Content caching is a widely studied technique aimed to reduce the network load imposed by data transmission during peak time while ensuring users' quality of experience. It has been shown that when there common link between caches and server, delivering contents via coded scheme can significantly improve performance over conventional caching. However, finding optimal content placement challenge in case heterogeneous behaviours. In this paper we consider number demands non-uniform popularity distribution homogeneous user preferences. We propose hybrid coded-uncoded trade-off diversity. derive explicit closed-form expressions server for proposed formulate corresponding optimization problem. Results show outperforms baseline pure uncoded previous works literature both
