In the wake of the devastating earthquakes that struck Turkey on February 6, 2023, causing widespread destruction and highlighting the vulnerabilities of existing communication and energy infrastructures, a new study proposes an innovative solution. Researchers Bilal Karaman, Ilhan Basturk, Sezai Taskin, Ferdi Kara, Engin Zeydan, and Halim Yanikomeroglu suggest integrating space-air-ground-sea networks powered by renewable energies to enhance resiliency during natural disasters. This approach aims to maintain critical communication services and energy supply even in the most challenging circumstances, thereby saving lives and aiding disaster response efforts.

The study aims to address the critical need for reliable communication and energy infrastructure during natural disasters. The researchers suggest using High Altitude Platform Stations (HAPS), drones, satellites, and renewable energy sources like wind and solar power. This multi-layered approach is designed to ensure that communication services remain operational, even in the toughest situations.

Aftermath of Turkey Earthquake

The Turkey earthquakes resulted in significant disruptions, with approximately 12 million mobile phone subscribers in the affected provinces experiencing communication breakdowns due to power outages. Although emergency measures were taken, including deploying satellite communications and mobile base stations, these efforts were often hampered by fuel supply issues for generators. This highlighted the need for a more resilient solution that could sustain operations without relying solely on traditional energy sources.

Multi-Layered Network Solutions for Disaster Resilience

HAPS, operating high above in the stratosphere, can cover large areas and quickly replace damaged terrestrial base stations. These stations can be powered by solar panels, making them self-sufficient. Drones equipped with cameras and sensors can provide real-time updates from the disaster zone, aiding rescue efforts. Ground-based networks, bolstered by direct communication technologies and advanced sensing systems, can maintain connectivity despite infrastructure damage. Additionally, sea-based networks using ships and unmanned surface vehicles can support communication in coastal areas hit by the disaster.

Energy sustainability is a crucial part of this plan. The researchers propose using Battery Energy Storage Systems (BESS), Electric Vehicles (EVs), and renewable energy sources to keep the communication networks running during power outages. Smart grids and microgrids can offer resilient power solutions, reducing reliance on traditional energy sources that may be compromised during disasters.

Strategies for Disaster Preparation

The study outlines two key strategies. The first is focused on pre-disaster preparation, using HAPS to manage network traffic and save energy during periods of low demand. This approach minimizes the need for additional ground-based infrastructure. The second strategy is designed for the immediate aftermath of a disaster, ensuring that communication remains intact through HAPS and protecting ground base station batteries from power failures. If necessary, EVs and mobile BESS can provide alternative energy sources.

Simulation results demonstrated the effectiveness of HAPS in restoring communication during disasters. The study showed that even a single HAPS could serve millions of users in the affected region, replacing all failed ground base stations and maintaining a high quality of service. Deploying multiple HAPS further improves service quality, providing robust and reliable communication even in densely populated areas.

Future-Proofing Disaster Response

Looking to the future, the researchers identified several challenges and research directions, including ensuring seamless interoperability between different network layers, managing communication latency, and optimizing resource allocation in dynamic disaster environments. Potential solutions include leveraging Artificial Intelligence (AI) and blockchain technologies for disaster communication planning, cloud-native deployments for network scalability, and energy harvesting techniques for user devices.

Integrating space-air-ground-sea networks with renewable energy technologies offers a promising approach to building disaster-resilient communication infrastructures. This innovative framework aims to mitigate the impact of natural disasters, ensuring timely and effective communication and energy supply, ultimately enhancing overall disaster response and recovery efforts.
