Existing IEEE 802.15.6 and IEEE 802.15.4 MAC protocols for WBANs lack support for emergency traffic and mobility adaptation, limiting QoS in eHealth applications.
This review highlights limitations in current IEEE 802.15.6 and 802.15.4 MAC protocols for WBANs and proposes a framework for evaluating future intelligent, QoS-aware designs.

Wireless Body Area Networks (WBANs) are vital for real-time health monitoring in eHealth systems. This article presents a comprehensive comparative analysis of MAC protocols based on IEEE 802.15.6 and IEEE 802.15.4 standards, with a focus on energy efficiency, latency, reliability, and emergency data handling. We critically examine superframe structures, access mechanisms, and adaptive MAC designs, and introduce a five-dimensional framework for protocol evaluation. Our study identifies key limitations in existing solutions-such as lack of support for emergency traffic and mobility adaptation-and outlines future research directions for developing intelligent, QoS-aware, and energy-efficient MAC protocols tailored to heterogeneous WBAN environments.
