## 5 The COGNIFOG Project
### Use Cases
#### 5.4.2 Trial 2--E-Health and Telemedicine Services  
Our second use case focuses on the provision of telemedicine services to construction workers at medium- to large-scale building sites. These construction projects frequently employ hundreds of personnel who work in difficult and safety-critical zones, which presents unique challenges in terms of safety and health monitoring. This trial is managed by Telematic Medical Applications (TNMA), a provider of telemedicine devices based in Greece. The primary requirement is to ensure the safety of the personnel through continuous monitoring and to provide a first-response telemedicine solution in case of emergencies. In such environments, workers are exposed to various hazards, including accidents, injuries, and health issues exacerbated by the lack of immediate medical facilities. These challenges can be addressed with the implementation of a robust telemedicine solution. This system must be capable of real-time monitoring of workers' vital signs, immediate detection of health anomalies, and quick initiation of medical consultations. In the use-case trial planned within the COGNIFOG project, a variety of edge and IoT devices are used. These include portable telemedicine systems that can be deployed on-site and wearable health monitoring devices for personnel. These are coupled with a cloud-based platform for data analysis and communication with medical staff. The portable \begin{table}

Table 2: Summary of benefits from adopting CEI continuum: Smart manufacturing. Each benefit is rated as _High_, _Medium_, or _Low_, indicating the level of impact, where _High_ reflects strong and direct influence, _Medium_ denotes partial or context-dependent improvements, and _Low_ indicates limited or indirect effects. telemedicine systems, designed as rugged and self-contained units, can be equipped with various medical sensors to conduct accurate health assessments. These systems facilitate real-time video consultations with medical professionals, ensuring workers receive timely medical advice and intervention. Wearable devices such as smartwatches can monitor vital signs like heart rate, blood oxygen levels, and physical activity. They also provide safety features like fall detection and SOS alerts, essential in hazardous work environments. The collected data is transmitted via secure, private networks established on-site, ensuring reliable communication even in areas with limited mobile network coverage. By utilising these advanced telemedicine solutions, the customer can ensure a safer working environment and prompt medical response, significantly reducing the risk of severe health incidents and improving overall operational efficiency. The COGNIFOG platform requirements for the Telemedicine use case emphasize autonomous deployment and management of edge and IoT systems to ensure consistency, scalability, and reliability. Rapid infrastructure setup is essential, enabling fast provisioning of IoT devices and telemedicine suitcases, ensuring that the cloud-to-edge-to-IoT system becomes operational quickly. Quick deployment of network services is critical for maintaining efficiency, while resilience to hardware and connectivity issues is necessary for continuous operation. Enhanced data security is achieved by processing sensitive information locally at the edge, with encrypted backups sent to the cloud daily.
