While routing through the Internet of Things (IoT) network, currently healthcare data packets do not get any special priority routing treatment. As IoT network is already facing performance issues due to network congestion, packet routing with conventional QoS process does not guarantee that the patients’ health data will be properly routed to doctors on time. This leaves the remote medical treatment at risk with possible threat to patients’ lives. In this paper, we studied the current healthcare packet transmission process in IoT and its performance issues in congested IoT networks, then proposed a sensor driven solution to prioritize healthcare data routing in congested IoT networks.Our proposed system adds a healthcare data identifier in IP packet headers at the sensor level, modifies QoS software at the network router level, and prioritizes healthcare data packet routing based on the healthcare data identifier seen at router QoS. Test data using TI Launchpad prototype shows that healthcare packets with identifier can route to doctor at 80% less latency than healthcare packets without identifier. Additionally, it saves medical diagnostic cost, and more importantly, reduces the risk of losing human lives. From our analysis, further contribution includes opening up multiple avenues for further research.
