An IoT-Based Body Area Network in Medical Care System: Related Challenges and Issues

The Internet of Things (IoT) is the collection of open intelligent devices. The fast development of IoT and the huge expansion of mobile technology are unveiling fresh growth opportunities in several areas, including education, transport, and farming and, in particular, healthcare. Introduction of IoT via medical applications has several advantages including cost savings by dropping hospital costs, health care costs, and transportation costs, costs of human resources and costs of insurance. Recently, the academic world has produced major progress in research and security development for IoT-based applications, particularly on IoT-based healthcare devices. It contributes to an additional benefit of enhanced healthcare quality. However, the increased use of IoT facilities in e-health applications, particularly in the insurance field, has resulted in increased security and privacy issues. Medical applications are prone to data violations and widening security problems due to the increase in access points to sensitive data through electronic medical records and the increasing popularity of wearable technology. So there is a need of an efficient lightweight, secure verification system, providing important security levels against various attacks, such as attacks by impersonation, a man in the middle attack and unidentified key-sharing attacks for IoT foundation E-health. This article presents a survey of problems, difficulties, and challenges a short analysis of multiple problems and problems suggested by different authors using different techniques and methods.
