Energy efficiency and sustainability are becoming increasingly important in information and communication technology. A key challenge is balancing availability, resilience, programmability, and energy efficiency in networks and services, which requires reliable monitoring, metrics, and benchmarking based on well-defined KPIs. The GreenNet Workshop focuses on emerging challenges and concepts for sustainable networked services, including sustainability across all network layers in light of growing AI/ML use, new access technologies, edge computing, and increasing demand for distributed services, intelligence, computation and data transport.
Authors are invited to submit original contributions of up to 7 pages in IEEE 2-column format (written in English). Only original papers not published or submitted for publication elsewhere will be considered for the workshop.
See https://netsoft2026.ieee-netsoft.org/ which includes author and submission guidelines.
