Energy Harvesting-Assisted Cognitive Sensor Nodes in Wireless Body Area Networks

This paper aims to propose and analyze an energy-and spectrum-efficient wireless body area network (WBAN) for smart healthcare applications. On one hand, we focus on improving the spectrum utilization in WBANs by incorporating an overlay cognitive radio (CR) paradigm that allows the co-existence of various sensor nodes as primary and secondary users based on their applications i.e., medical or non...
