A reference is missing in our paper [1]. Figure 2 was adapted from Reference [2] with permission. The figure is listed and described as below:

WBANs application in the medical field are composed of wearable and implantable sensors that can detect information from the human body and send it to a central unit as shown in Figure 2. These sensors have some characteristics such as small, low-power detection and have the capability to detect medical signals data from the control unit. There is a difficulty in the monitoring devices that are not completely wearable where the wires are used to connect many sensors. Yuce [2] explored a vision to the future of medical sensor networks should be miniaturized and also wearable sensors that can communicate with the receiving device wirelessly.
