Home area network for optimizing telehealth services--empirical simulation analysis.

Area of Science:

• Computer Science
• Network Engineering
• Health Informatics

Background:

• Telehealth applications, including Video-over-IP and remote sensor monitoring, are increasingly used in patient homes.
• These delay-sensitive applications require high quality of service (QoS) and bandwidth priority.
• Home Area Networks (HANs) often lack traffic management, degrading Telehealth performance as device numbers grow.

Purpose of the Study:

• To propose an infrastructure-based method for improving Telehealth application quality within a HAN.
• To manage and optimize Internet traffic distribution among connected devices in a home environment.
• To address the urgent need for network management in expanding HANs supporting Telehealth.

Main Methods:

• Setting up a simulated HAN environment using readily available home devices.
• Testing the proposed traffic management method with typical Telehealth application traffic (Video-over-IP, VoIP, multimedia).
• Evaluating the impact of the management system on packet loss and CPU load under background traffic.

Main Results:

• The proposed method demonstrated improved service quality for Telehealth applications.
• Achieved approximately 11% less packet loss under 12Mbps background traffic.
• Resulted in a 10% increase in CPU load for traffic management functions.

Conclusions:

• The developed infrastructure-based method effectively enhances Telehealth application quality in HANs.
• The system provides a viable solution for managing network traffic to support critical healthcare services at home.
• Optimizing HAN traffic management is crucial for reliable and satisfactory Telehealth experiences.
