The Internet of Things (IoT) was developed through information improvement and communications technologies. As IoT technologies used in a multitude of health settings make life easier for doctors and clients in the current medical system. The IoT advancements to medicine would be the Body Sensor Network (BSN) platform allows for the monitoring of patients utilizing a network of wireless sensor nodes were lightweight or small-powered. Furthermore, the lack of security considerations in creating this modern technology for health systems compromises medical confidentiality. The primary protection needs for a BSN-based modern healthcare system were initially highlighted. Therefore, proposedBSN-Care, an effective IoT-based medical system that allows BSN to efficiently address these needs.
