Content-Centric Collaborative Edge Caching in 5G Mobile Internet

The fifteen articles in this special section explores expositions on novel functionalities and technologies in various wireless and mobile network caching equipment, with respect to caching algorithms, caching implementations, system integration, cache modeling, optimization, and so on. In recent years, with the rapid development of information and communication technologies (ICTs), mobile network operators are increasingly suffering from the traffic explosion problem. And this problem remains to be tackled in the upcoming fifth generation (5G) networks. However, due to the limited bandwidth, the need to save energy, and the fact that advancements in transmission techniques are approaching the Shannon limit with diminishing returns, it is clear that these advancements need to be complemented by improvements in the network, transport, and application layers to provide sustainable solutions toward richer network capacity.
