A Survey on Wireless Body Area Network : Characterstics , Architecture , Challenges

People have benefited from the recent advancement and spread of new techniques in a variety of ways. Most importantly, this has become increasingly linked to healthcare information exchange digital services. Remote patient monitoring is among the most important services, since it allows healthcare professionals to check, assess, and treat people without needing to be personally there. Biosensors that have been miniaturised have the advantage of being able to be implanted in, on, or off the bodies of individuals, and then they can relay physiologic data via wireless to cloud computers. This technique is known as a Wireless Body Area Network. This paper discusses WBAN architecture, WBAN telecommunication, WBAN impediments, and many other aspects of WBAN. WBAN faces a variety of challenges in terms of obtaining a high standard of security because because of its resource constraints and critical applications. This paper presents a comprehensive review of WBAN technologies, focusing on confidentiality as well as upcoming study objectives.
