Abstract
A wireless body area network (WBAN) is made up of small health-monitoring sensors that are implanted or placed on the human body. These sensors collect and transmit human medical and physiological data . WBANs are linked to medical servers that observe the health of patients. Because of its ability to continuously and remotely monitor patients' health, this type of network can save critical patients.WBAN is being used to establish communication links between these sensors and provide feedback to users. To provide mobility, sensor nodes must perform on electric power. As a result, the most crucial problem in WBAN is low energy consumption. It is difficult to replace the batteries in in-body sensors. To resolve this problem, we present an Neutrosophic -Promethee (Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE)method for choosing the selection of relay node, in which AHP calculates the weight of different criteria and and forwards them to the promethee technique which used for outranking them. The experimental outcomes of this study indicate that energy utilization and overall network reliability are significantly reduced. Keywords:WBAN, MCDM method, Neutrosophic method, Promethee method.
