Wireless Body Area Network (WBAN) refers to a network on the human body. The energy consumption
of biosensor nodes affects the performance of wireless body sensor networks (WBSNs). Vital nodes can
be implanted or worn in the patient's body and vital signs monitored. A new design of a mathematical
model for calculating the energy consumption of the front and rear WBSN of the human body is
proposed. It was developed to enhance wireless body networks. Energy savings for biosensor nodes in
WBSN is achieved by adding relay nodes to WBSN. The energy saved is calculated based on the
approach proposed in this paper. This technique is the relationship between the biosensor nodes, the relay
nodes, and the pelvis nodes on the front side of the body and on the back of the body. The performance of
a wireless body area network, which uses relay nodes to reduce power consumption, has been studied. A
new mathematical model is presented to provide energy consumption for the biosensor nodes. After
testing this model, it was found that the percentage of energy consumption for the sensor nodes was
reduced by up to 72%, which proves the efficiency of the model. The test was done with (MATLAB2021B).
