چکیده مقاله:

An efficient energy transmission has been crucial especially in the area of Wireless Sensor Network (WSN).In WSN, the nodes working on limited battery power that reduce its life span. As a result, it will draw more power. The application of WSN usually can be found in industrial automation, military, agriculture, and environment monitoring. The use of error-correcting technique is vital in reducing the bit error rate (BER). Therefore, the main objective in this research paper is to investigate the performance of BPSK and QPSK under different fading channel. The method of measuring the performance is by evaluating BER and Signal-to-Noise Ratio (SNR). Lastly, the works in this research paper can be extended in the future for better performance analysis with more advanced modulation technique.
