Wireless Body Area Network (WBAN) has turned into an important field of research that could give the solution for healthcare monitoring of human body. Clients of WBANs are expanding exponentially as more individuals are grasping wearable checking gadgets for various social insurance causes. Interference is one of the real issues in WBANs, which emerges principally because of closeness of different WBANs, irregular human portability, and disseminated nature of individuals conveying WBANs. In this paper, we proposed an agent node selection scheme based upon EMR-Rules (efficient mitigating rules) enhance its Quality of Service (QoS) parameters. EMR gives great arrangements if there is any vulnerability or incomplete truth in input factors. When the latency or cost exceeds the desired value's either degrades, then the link has interference then we select any agent node available in the network to the source node. On this set of rules, link with the highest hyperlink value is preferred and in this manner, agent node is chosen and it will hold transmitting the records to the sink node. Till the damaged node is reset. This technique offers improvements in strength efficiency and packet delivery ratio. © 2020 IEEE.
