A Comprehensive Review on Wireless Body Area Network - Technologies, Challenges, Application and Energy Saving Techniques

A Wireless Body Area Sensor Network (WBASN) is becoming a routine part of everyday life due to its versatility of uses, particularly in the field of medical care for continuous patient monitoring, providing clinical assistance in patient care, and to improve the quality of patient’s lives. Due to the low power battery capacity of biosensors comprising in WBAN, making replacement of batteries poses a challenge, specifically for sensors implanted inside the human body. Also, these networks produce a large amount of sensory information, which requires the network to balance the load to perform optimally and last longer. This review article gives an outline about energy management of wearable or non-wearable sensors, load balancing, routing, and security issues in wearable Remote Body Area Network (RBAN). It also highlights the fundamental issues, energy maintaining challenges in such delicate sensitive BAN, and a wide scope of Internet of Things (IoT)-based applications in the field of clinical, sports, lifestyle, and diversion. Various energy-improving routing algorithms utilized in WBAN to profit the networks Quality of Service (QOS) and the correspondence advancements utilized in associating wearable WBAN in the IoTapplication are also discussed in detail.
