Abstract: Wireless Body Area Networks (WBANs) applications have emerged as one of the most recent research areas of wireless sensor networks. Lots of research is improving QoS factors in sensor networks. However, QoS requirements vary from application to application, WBAN applications are very sensitive, and QoS issues in WBAN need major concern and focus. This paper outlines the WBANs QoS requirements and factors and reviews with emphasis on their strengths some medium access mechanisms that response to some QoS challenges. Moreover, the authors have defined and specified a QWBAN MAC protocol that can allow the integration of QoS architecture over WBAN. A set of QoS modules such as admission control (CAC), bandwidth allocation and scheduling are discussed. Besides that, an integrated QoS architecture is suggested for WBAN to support healthcare applications.
