Abstract

In this paper, we investigate the energy efficiency of a IEEE 802. 15. 4 based RF transceiver using Direct Sequence Spread Spectrum- Offset Quadrature Phase Shift Keying (DSSS-OQPSK) modulation under 2. 4 GHz frequency band in a WSN. Multi path propagation in a wireless environment affects the reliability of the network and therefore the sensor nodes wastes the battery power to ensure successful delivery of data by adopting Automatic Repeat reQuest (ARQ) schemes. Error control coding is one of the most suitable solutions to this reliability issue. In this paper, the use of one such Forward Error Correction (FEC) codes such as Luby Transform (LT) codes to reduce energy expenditure by the network nodes is analyzed under Rayleigh fading channel environment. The performance metrics considered for our study are Bit Error Rate (BER) and Energy spent per bit. Simulation results show that LT codes show improved performance under severe fading channel conditions, i. e. , for low SNR values (-5 to 2 dB) and ARQ scheme provides better performance under high SNR values (above 2 dB).
