Welcome to The 22nd IEEE International Conference on Green Computing and Communications (GreenCom-2026).

Computer networks, communication systems, and other IT infrastructures have a growing environmental footprint due to the significant amounts of energy consumption and greenhouse gas emission. To address such problems and create a sustainable environment, new energy models, algorithms, methodologies, platforms, tools and systems are required to support next-generation computing and communication infrastructures. Thus, green computing and communications solutions should be designed to better integrate renewable energy sources, to improve energy efficiency, and to reduce greenhouse gas emissions and harmful materials.

Topics of interest include, but are not limited to:

Track 1: Green Computing and Communication Technologies

• Green infrastructure sustainable design and technologies
• Energy- and power-constrained devices and gateways
• Ultra-low power systems architectures
• Low-power, distributed data processing on sensors
• Energy-efficient M2M wired and wireless communications and networking
• Optimization and/or analysis in green computing and communications (including core network optimization)
• Green big data, cloud, and data center architecture
• Green technologies for 5G (SDN, IoT, and crowdsourcing, etc.)
• Energy harvesting communications and networks

• Smart metering infrastructure and technologies
• Large-scale monitoring, control and demand response
• Advanced data fusion, mining and modeling in smart grid
• Management and control of distributed energy generation, storage and consumption
• Advanced smart grid applications: grid-to-vehicle and vehicle-to-grid, Micro-grid

• Smart sensing systems
• Smart city
• Green vehicle, green home, green buildings and green anything
• Green industrial automation and control
• Intelligent Transport Systems and control
• Energy efficiency in aerial/UAV communication networks
• Green social networks
• Applications of blockchain in energy management and trading

All papers need to be submitted electronically through the conference submission website (https://hpcn.exeter.ac.uk/greencom/) with PDF format. The materials presented in the papers should not be published or under submission elsewhere. Each paper is limited to 8 pages (or 10 pages with over-length charge) for a regular full paper, 6 pages (or 8 pages with over-length charge) for a full paper including figures and references using the IEEE Computer Society Proceedings manuscripts style.

Papers accepted by IEEE GreenCom 2026 conference will be published by the IEEE Computer Society Press. At least one author of each accepted paper is required to register and present their work at the conference; otherwise, the paper will not be included in the proceedings. All accepted papers will be submitted to IEEE Xplore and EI. Distinguished papers presented at the conference, after further revision, will be invited for submission to a special issue.
