An Efficient Energy Aware Secure Routing in Medical Data Transmission for Body Sensor Network

Abstract: The Body Sensor Network (BSN) technology is one of the most imperative technologies used in IoT-based modern healthcare system. Then, we process a secure IoT based healthcare system using BSN, called BSN-Care, which can guarantee to efficiently accomplish those requirements. BSN architecture composed of wearable and implantable sensors. These sensors collect the physiological parameters and forward them to a coordinator called Local Processing Unit . The LPU works as a router between the BSN nodes and the central server called BSN-Care server, using the wireless communication mediums such as mobile networks 3G/CDMA/GPRS. We adopt a Time Division Multiple Access (TDMA)-based protocol and dynamically adjust the transmission order and transmission duration of the nodes based on channel status and application context of WBAN. The Body Sensor Network technology is one of the core technologies of IoT developments in healthcare system, where a patient can be monitored using a collection of tiny-powered and lightweight wireless sensor nodes. In this process, at first, we highlight the major security requirements in BSN-based modern healthcare system. Subsequently, we propose a secure IoT-based healthcare system using BSN, called BSN-Care, which can efficiently accomplish those requirements.
