Research on Energy-efficiency in Wireless Sensor Networks Based on Minimum Energy Coding

Abstract

The energy consumption of an OOK transmitter was analyzed． A simple and energy efficient source coded ME-Coding On /Off Keying modulation scheme for wireless application was presented． The SNＲ performance of ME-Coding OOK was better than other modulation methods in a bit low rate． However， when the circuit energy consumption is taken into account，the simulation results demonstrate that the total energy consumption of the classical system model can not be reduced． It proposes a new system model which matches the ME-coding OOK communication to get the total energy optimization．
