While proceeding towards the age of Internet of Things (IoT), Wireless Sensor Network (WSN) is going to play an indispensable role in the overall networking architecture. Applications like health care, smart-city etc. are extensively using WSN frameworks to collect and analyse real-time data along with taking necessary actions based on the application’s requirements. While designing the routing protocol for WSN, the uniqueness and requirements of the application have the potential to play a dominant role. Generalizing the networking framework while ignoring application-specific requirements would lead towards designing an inefficient routing protocol. Considering these scenarios, we have proposed an application-specific routing protocol for the health care which would ensure the increase in network lifetime while maintaining the maximum throughput in data transmission. The proposed routing protocol has shown an improved performance in terms of metrics like throughput, network lifetime, end to end delay, packet delivery ratio and packet loss while comparing with some of the traditional routing protocols e.g. Routing Protocol for Low-Power and Lossy Networks and Collection Tree Protocol.
