In the next-generation wireless networks, there have been explosively increasing wireless data services, such as video streaming, push media, mobile application download/updates, and mobile TV. These new services involve both intensive communication and computation, and to meet these requirements edge caching and computing has been recently proposed.

Caching brings content closer to users by pre-fetching the content during off-peak times and hence can greatly reduce network congestion and improve the user-perceived experience. Moreover, edge computing can help alleviate the computation load on the central node, by offloading the computation tasks into edge nodes through wireless transmission links.

Despite the development of edge caching and computing, some fundamental problems are still open and require immediate studies, such as:

- How can we achieve an ultra-high gain from edge caching to support the ultra-high data rate and low latency?

- How can we incorporate edge caching and computing into devising the transmission strategies for the next-generation wireless networks?

- How can we design novel information security strategies by taking into account the effect of edge caching and comuputing?

- How much gain can we obtain from the integration of communication, caching and computing (3C)?

- Are there any new applications for edge caching and computing to benefit wireless networks?

This Special Issue aims to bring together leading researchers and developers from both industry and academia to discuss and present their views on all the aspects of edge caching and computing wireless networks. Both original research and review articles are welcomed.

Potential topics include but are not limited to the following:
