Special Issue Information
Dear Colleagues,
Goal-oriented communication represents a paradigm shift from traditional communication networks, which prioritize bit-level accuracy, towards achieving specific tasks with a focus on efficiency, relevance, and timeliness. This framework addresses the growing demands of IoT, cyber–physical systems, and upcoming 6G infrastructures, aiming to transfer only the information needed to fulfill a desired objective.
The concept of freshness has evolved over the past decade with the metric Age of Information (AoI), which assesses the timeliness of information in decision-making and control. As research has progressed, the metric has expanded to include the Semantics of Information (SoI), which shifts the focus from information timeliness to the significance of information, enhancing decision-making processes by prioritizing data that are not only timely but also purpose-driven and contextually significant. Metrics such as the Value of Information (VoI) and Age of Incorrect Information (AoII) partially illustrate the SoI. In relation to the SoI, estimation theory seeks to infer unknown states from observed data. While traditional estimation focuses on minimizing error variance, integrating semantics means emphasizing estimation outcomes that enhance system performance. Incorporating AI/ML-based methods into these metrics is another dimension of research that allows one to not only design tailored optimization algorithms and protocols, but also to understand the relationships among metrics and their impact on goal-oriented communications.
We invite contributions in but not limited to the following areas:
- Age and Semantics of Information in multi-agent systems;
- Freshness and semantic-aware remote estimation in networked systems;
- Distributed learning for goal-oriented communications;
- Freshness and semantic-oriented massive access in IoT;
- Freshness and semantic-based dynamic resource allocation;
- Theoretical relationships among freshness, semantics, and estimations.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
