and anywhere. The main objective of this chapter is to explore body area network communication technologies driven by AI. Medical AI mainly utilizes computer network topologies to perform monitoring, recording, diagnoses, and treatment process [21].

      Communication in the body sensor network is of two types.

      1 (i) In-body communication uses RF signals between sensory nodes, which are implanted in our human body. The frequency at which the communication has to take place is defined by Medical Implantable Communication Service (MICS), and the range of frequency is 402–405 MHz

      2 (ii) On-body communication is the communication between wearable sensory nodes, which consists of biosensors. Ultrawideband (UWB) can be used for on-body communication. IMS based, which is mainly used for industrial, medical, and scientific applications having a range of 2.4–2.485 GHz. Many electronic applications operate on this band.

      1.4.1 Features

      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.

      1.4.2 Communication Architecture of Wireless Body Area Networks

      Stage 1: Intra sensor communication

      The communication among the sensors around the human body is considered in this stage. A personal server acts as a gateway, which is used by communication signals within the human body. Gateway transfers the data to the next stage of architecture.

      Stage 2: Medium

      This stage enables the data transfer between the personal server and user through an access point, which is considered as a central unit of the network, which can make decisions in case of emergencies.

      Stage 3: Beyond WBAN

      Smartphones are used to interlink between the access point and medical server, in which patient historical data could be stored. The medical environment database is a very sensitive part of stage 3. Security against this stage is fulfilled to protect the personal history of the patients.
