Network security is designed to protect the usability and integrity of different network and data. It makes efficient and effective access to the system. It finds a variety of threats and stops them from entering or spreading on our web. A body sensor network (BSN), is a wireless network of wearable devices. A human health monitoring platform designed and developed under the application of the body sensor network. Internet of Things (IoT) is a new concept that is to allow users to connect various sensors and smart devices to collect real-time data from surroundings. This paper presents a novel approach for data transmission, security, and reliability and proposed architecture based on the cognitive model to realise coaching system for daily life activities. Also, it introduces a structural health monitoring framework, used to collect data from multiple data sensors to make intelligent and reliable monitoring. This paper also proposes a secure and reliable body-sensor network based on the Internet of Things. It is a new model introduced to the overall health of the patient. It stimulated and implemented through strong pro activities of the patient and realised using mobile devices. Visions for future health-care IoT and some future research methods are proposed.
