CoAP-based healthcare sensor networks: A survey
Hasan Ali Khattak, Michèle Ruta, Eugenio Di Sciascio · 2014
The Internet of Things (IoT) vision is a hot research topic which enables all kinds of devices to connect together and share information seamlessly. IEEE 802.15.4 Low power Wireless Personal Area Networks (LoWPAN) and IPv6 over LoWPAN (IETF 6LoWPAN) defines standards and protocols for resource constrained Wireless Sensor Networks (WSN). Constrained Application Protocol (CoAP) is an emerging application layer protocol supporting resource constrained devices and easy integration with the existing TCP/IP standards. It is particularly useful for advanced applications in the healthcare field. This paper surveys technologies and techniques for using CoAP-based WSN for connecting and monitoring medical sensors. Application requirements for creating healthcare WSNs utilizing IPv6 and CoAP and real-time monitoring issues are also discussed.
