Distributed Caching for Data Dissemination in the Downlink of Heterogeneous Networks
Distributed Caching for Data Dissemination in the Downlink of Heterogeneous Networks
Heterogeneous cellular networks (HCNs) with embedded small cells are considered, where multiple mobile users wish to download network content of different popularity. By caching data into the small-cell base stations, we will design distributed caching optimization algorithms via belief propagation (BP) for minimizing the downloading latency. First, we derive the …
