The wireless body area network (WBAN) is a branch of the sensor (WSN) intended for tracking essential patients’ physiological signals and transferring this knowledge to coordinator. During routing data, WBANs encounter critical problems like WSNs. Moreover, particular constraints make it more challenging that they need be addressed. This survey article categorizes briefly analyzes range current...

Wireless body area network (WBAN) can be applied to a variety of scenarios, such as physical training, patient care, and health monitoring for the aged. To prolong lifetime WBANs respond an emergency, energy efficiency age information (AOI) become two most important performance indicators. The dynamic characteristic makes link quality wireless communication vary intensely, which brings challeng...
