Various sensors such as temperature, heart rate monitor utilizing electrocardiography, and accelerometer to detect fall and seizure conditions were integrated in the WBAN. Sensed data is wirelessly transmitted to the central control unit (CCU) that is associated with a remote base station. For benchmarking, medically certified sensors were employed to validate wearable sensors data. The sensor information can be ported in the cloud environment using CCU-based gateway with Global System for Mobile communication (GSM) modem capability. This mechanism is facilitating remote access to sensors information. To connect Radio Frequency (RF) units wirelessly, Zigbee mesh topology was adopted. In this way, they can be remotely overseen, managed and controlled by assigned staff. The presented prototype featuring the desired WBAN system performance was evaluated with different human postures and moving scenarios. & WIRELESS BODY AREA network (WBAN) platforms have evolved significantly over the last Digital Object Identifier 10.1109/MCE.2019.2953736 Date of current version 7 February 2020. March/April 2020 few years. These typically integrate sensing and radio modules for remotely observing patient health and physical parameters.1,2 With WBAN, individuals can easily keep track of their beloved ones in addition to healthcare professionals while they are away.
