Minimization of Energy Consumption for OOK Transmitter Through Minimum Energy Coding

Résumé

Energy consumption of Wireless Sensor Networks (WSNs) includ- ing On/Off keying (OOK) transmitter is important for short range transmis- sion and long battery life time requirements. In order to improve the energy efficiency of an OOK transmitter, the Minimum Energy (ME) coding strategy is adopted in this paper. We first give the energy consumption model based on a real OOK transmitter, which has an energy efficiency of 52 pJ/bit by completely switching off the transmitter during the transmission of low bit ’0’ . Based on this energy consumption model, ME-Coding provides an energy efficiency of 30 pJ/bit for coding size k = 3. Moreover, larger coding size offers more significant improvement, at the sacrifice of spectral efficiency and trans- mission range. In this paper, we have also determined a closed-form solution for the optimal coding size for a given transmission range constraint.
