The IFIP WWIC 2019 conference welcomes submissions from academia and industry that explore challenges and advances in architectures, algorithms, protocols, and technologies for a global wired/wireless Internet network. Papers that present original work, validated by experimentation, simulation, or analysis, are solicited. We also encourage work-in-progress and position papers that describe highly original ideas, present new directions or have the potential to generate insightful provocative discussions. Extended versions of selected papers will be invited for publication on a fast track special issue of Computer Communications (Elsevier) journal.
