Hence energy is limited. Hence optimization of energy is a critical factor for the sensor node's lifetime. Here we have considered the asymmetric method of communication that uses different modulation schemes with error correcting codes for up-link and down-link communication. We evaluate and compare two extensively used error correcting codes, Hamming and Reed-Solomon (RS) codes, together with well-known modulation schemes, including QAM, M-FSK, M-PSK, and BPSK. This paper makes use of the relation between Signal to noise ratio (SNR) and bits per symbol towards modelling and analysis purposes. © 2023 IEEE.
