Abstract

In the context of renewable energy facilities, ensuring continuous and reliable network connectivity is critical for monitoring, control, and optimization of energy production. As these facilities often operate in remote or resource-challenged locations, maintaining connectivity during catastrophic events, in under developing nations, or in conflict zones becomes a significant challenge. This article explores a proposal for the integration of Delay Tolerant Networks (DTNs) as a robust solution for addressing connectivity issues in such environments. DTNs are designed to operate effectively even with intermittent or unreliable communication links, making them ideal for scenarios where traditional communication infrastructure is unavailable or damaged. The paper discusses the importance of maintaining an always-on connection to enable real-time data collection, fault detection, and system adjustments, which are essential for efficient renewable energy operations. Additionally, cybersecurity concerns associated with remote renewable energy networks are highlighted, particularly in vulnerable regions. Cyber threats targeting critical infrastructure in unstable regions could compromise the reliability and safety of energy systems. The article examines methods for enhancing cybersecurity in DTN-based networks ensuring that the integration of these networks does not expose energy systems to malicious attacks. A novel approach is, also, presented for a secure and resilient communication with DTN between Renewable Energy Facilities with the introduction of a mobile node for extremely severe communication scenarios. At last, this work is the first step towards the evolution into a future prototype phase.

Key words: DTN, IoT, Renewable Energy, Renewable Energy Facilities, Cybersecurity.
