Objectives: To save the energy consumption of the sensors in transmission so that they may operate for longer time span. Methods/Statistical Analysis: It is suggested to use eight sensors placed on the human body and then transposition has been applied to all of these sensors to reduce the distance of each sensor from the sink. Path loss was calculated after transposition in terms of distance and results were compared with the existing schemes. Euclidean distance technique was applied to calculate the distance values and then observed for their positions. Findings: In this investigation, the main parameter is the path loss which needs to be reduced so as to make the transmission better and to make network stable. The findings are unique in the sense that with the help of the proposed values of sensor positions a routing protocols be designed which will have a better network stability and network life time and this will be achieved as the sensors will deplete less energy during transmission. The main idea behind this research is to find the most suitable sensor locations on the body where they can consume less energy during data transmission to sink and have more life to operate. Application/Improvements: The proposed scheme is applicable to body area systems which have limited energy sources due to the size of the sensors. The proposed scheme is compared with two existing schemes and there were improvements in terms of path loss parameter.
