Abstract :
In wireless sensor networks due to the small transmission distances involved, the computation energy along with the radio energy determines the battery life. Energy consumption of error control codes (ECCs) is a complex function of the energy consumption in computing encoding-decoding, transmitting "redundant" bits and energy saved by coding gain. This paper presents a methodology, which integrates computation and radio energy for searching an energy optimal ECC. Based on this methodology, a design space exploration framework and the energy model of sensor node have been developed. Exploration results show that the energy optimal ECC saves 15-58% node energy for given parameters.
