Communications, caching, and computing for content-centric mobile networks: Part 2 [Guest Editorial]

This is Part 2 of a Feature Topic (FT) series covering the convergence of communications, caching, and computing for next generation wireless mobile networks. The design and engineering philosophy of modern wireless networks is witnessing a fundamental shift from being "connection-centric" to being "content-centric". This FT aims to provide a comprehensive overview of recent progress in the theoretical foundation, architectural advances, modeling/analytics, protocol engineering, and prototyping of content-centric mobile networks. The response to our Call for Papers was overwhelming, with a total of 54 articles submitted by leading researchers and practitioners from around the world. Following a rigorous review process, Part 1 of this FT series, containing 12 articles, appeared in the August issue of IEEE Communications Magazine. The following additional six papers are selected to be included in Part 2 of the series.
