Routing with QoS and Fault Tolerance in WBAN: The HEALTH Protocol

Abstract

The Internet of Things (IoT) is a technology for connecting physical objects through various digital systems, applied in many fields, including medical monitoring. In this context, Wireless Body Area Net works (WBANs) integrate seamlessly into the IoT infrastructure. The increasing adoption of WBANs in the medical sector is driven by their numerous advantages, such as continuous patient monitoring, early detection of health risks, and the provision of personalized medical care. However, several challenges remain, including managing energy consumption, ensuring consistent QoS, resilience to failures, and maintaining patient comfort. This study presents an innovative routing protocol, HEALTH, specifically designed for WBANs, aiming to ensure optimal service quality in terms of temperature, response time, energy consumption, and delivery rate. The protocol’s performance was evaluated using the BNS and Castalia frameworks, based on the Omnet++ simulator. Simulation results confirm the protocol’s effectiveness while maintaining sustained service quality.
