It is essential to develop energy-efficient communication techniques for nanoscale wireless communications. In this paper, a new modulation and a novel Minimum Energy Coding scheme (MEC) are proposed to achieve energy efficiency in Wireless Nano-Sensor Networks (WNSNs). Unlike existing studies, MEC maintains the desired code distance to provide reliability, while minimizing energy. It is analytically shown that, with MEC, code-words can be decoded perfectly for large code distances, if the source set cardinality is less than the inverse of the symbol error probability. Performance evaluations show that MEC outperforms popular codes such as Hamming, Reed-Solomon and Golay in the average codeword energy sense.
