Submission Guidelines

Authors are invited to submit original unpublished manuscripts that demonstrate current research on real-life modeling in 5G/6G networks and beyond related to REFRESH workshop’s topics of interest. Please use the US letter size (8.5 × 11 in) in standard IEEE conference LaTeX format or Microsoft Word template available on the link below: Template

All submissions should be written in English and submitted as a full or work-in-progress paper. Full papers should have a maximum of eight (8) printed pages including figures and references. Full papers are expected to describe fully developed ideas with a thorough evaluation. Work-in-progress papers should have a maximum of four (4) printed pages including figures and references. Work-in-progress papers are expected to describe new and interesting ideas that have not yet reached full maturity. Note that REFRESH does not follow the double-blind review policy. The names and affiliations of all the authors must be present in the submitted manuscript.

Accepted and presented papers will be published in the DCOSS-IoT 2026 conference proceedings and submitted to IEEE Xplore as well as other Abstracting and Indexing (A&I) databases.
