An Application-Agnostic Quality of Service Framework For Wireless Body Area Networks

This paper presents an application-agnostic Quality of service (QoS) framework for Wireless Body Area Networks (WBAN). The applications of WBAN includes several areas such as smart health care, assisted elderly living and emergency response. In the WBAN, obtaining an acceptable QoS performance is extremely important due to its relation with human health and emergency situation. The QoS requirements of a sensor in WBAN is tightly related to the context of its application. Therefore, successful design of a QoS frameworks needs to be application context-aware. In this paper, we propose a context-aware framework to guarantee the QoS requirements of the sensor nodes in the WBAN. Our framework is implemented as a separate module which is independent of the application layer and can be utilized for different medical applications. Additionally, our framework enables the medical application to dynamically adapt to the QoS changes due to the nature of application and patient's health status.
