Abstract

In WBAN, a number of implantable, wearable and off-body biomedical sensors are utilized to monitor various vital signs of
patient’s body for early detection, and medication of grave diseases. In literature, a number of Medium Access Control(MAC)
protocols for WBANs have been suggested for addressing the unique challenges related to reliability, delay, collision and energy
in the new research area. The primary goal of MAC protocols in WBAN is to efficiently analyze their features and endure energy
minimization . In this paper, we provide a comprehensive survey of energy-efficient MAC protocol for wireless body area networks.
