Healthcare Tech Gets a Boost with Smart Congestion Control

The Internet of Healthcare Things (IoHT) has revolutionized patient care by enabling real-time monitoring and emergency services. However, a major challenge arises when a huge number of messages from various sensors flood the network during emergencies, causing congestion and potentially life-threatening delays.

Current congestion avoidance methods rely on priority queues or First-In-First-Out (FIFO) scheduling, but these approaches have limitations. They struggle to distinguish between different levels of emergency, leading to delayed or lost transmissions. This is where a new approach comes in - one that uses a dual queue structure to handle high and low-priority packets more effectively.

This innovative scheme works by classifying packets based on their source and assigning an emergency flag to indicate their level of urgency. High-priority packets are then placed immediately after the packet currently being processed, ensuring they receive timely attention without disrupting ongoing transmissions. This smart repositioning mechanism allows critical packets to be served quickly, making a significant difference in emergency situations.

Simulations using NS-2.35 on Ubuntu have shown impressive results. The new scheme reduces buffer loss probability and high-priority packet loss significantly - up to 80% lower buffer loss and 90% fewer emergency packet drops compared to existing methods. By minimizing delays and packet loss, this technology has the potential to greatly improve the performance of IoHT networks and ultimately enhance patient care.

The key to this scheme's success lies in its ability to prioritize emergency packets effectively. By doing so, it ensures that critical information is transmitted quickly and efficiently, even in the most congested networks. This is a major breakthrough for IoHT, as it enables healthcare providers to respond rapidly and effectively in emergency situations.
