Wireless Body Area Networks (WBANs) provide monitoring of physiological data without compromising patient mobility. In order not to affect patient health nor his/her mobility, nodes in a WBAN transmit data using short range and low power radio frequency electromagnetic waves. WBAN transmissions thus become subject to failures caused by interference or body mobility. Additionally, WBAN applications typically have timing constraints and dynamic traffic, which can change depending on the patient’s physiological conditions. Several approaches to the Medium Access Control (MAC) sublayer have been proposed to WBANs in order to improve reliability and efficiency of these networks. In this paper, we propose and use a systematic review method to cover MAC approaches to WBAN efficiency and reliability under dynamic traffic, interference and body mobility.
