In this paper, the authors 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.
