Blockchain-Enabled Smart Health Monitoring System in WBAN

Abstract

The rising need for continuous health monitoring due to unhealthy lifestyles has spurred interest in Wireless Body Area Networks (WBANs). WBANs employ biosensors worn on the body to assess various health indicators, transmitting data wirelessly to doctors for analysis while ensuring patient confidentiality. However, the limited power of biosensors necessitates energy-efficient data transmission for prolonged functionality. Moreover, ensuring data security is paramount. Blockchain technology, known for its secure and decentralized nature, offers a solution. By integrating blockchain with WBANs, or “healthchain,” data confidentiality and integrity can be preserved while facilitating efficient routing protocols. This fusion promises to revolutionize healthcare by securely storing patient data and facilitating its utilization by medical professionals.
