In Wireless Sensor Networks, energy efficiency is a very critical issue because sensor nodes have limited battery resources. The relationship between the number of transmitted bits, Estx, and ESB, a more energy-efficient communication protocol can be designed, thereby extending the lifetime of the sensor network. This study uses approaches with the Nelder Mead Simplex method. This study to estimate Estx and ESB based on the number of transmitted bits. The study was conducted using sensor nodes to measure the energy used in transmission and standby mode. The obtained data were analyzed using certain statistical techniques to evaluate the relationship between the number of bits, Estx, and ESB. The results show that the number of transmitted bits has a significant effect on Estx and ESB. It is found that the optimal Estx and minimum ESB can be achieved by adjusting the number of transmitted bits, which has implications for reducing the total energy consumption in the network. In addition, a linear relationship between the number of bits and Estx can be found, while ESB can be minimized with appropriate energy saving strategies. This study makes an important contribution to the field of Wireless Sensor Networks by offering practical guidance for designing more energy-efficient communication protocols. The findings in this study show that the best modulation to determine the optimum Estx and minimum ESB is 16 QAM modulation. In addition, the use of the best modulation can be used to determine the optimum Estx and minimum ESB values influenced by the number of bits. These findings are expected to improve operational efficiency and extend the life of wireless sensor networks, supporting various WSN applications more effectively. © 2024 IEEE.
