Since the nodes are placed inside and outside the human body, it requires less power consumption as the devices are battery operated. So, it is essential that for the battery to work longer, power consumption should be less. As communication deals with bio-signals in the medical field, the Quality of Service (QoS) plays an important role. So, the user can detect proper information and treat accordingly.

As the network deals with information transmission related to vital parameters of human beings, the security of data is critical to avoid unauthorized accessibility. In the case of biosensors, the threshold value is set. So, if any parameter increases or decreases below the threshold value, then it generates an alarm, so fewer false alarms are required. Wireless Medical Telemetry Service (WMTS) and UWB are technologies that are used for body monitoring systems because of their low transmission power.
