<strong>Abstract</strong><br>
The Proliferation of personal wireless enabled devices in the past few years; for instance cell phones, laptops and 
PDAs; have made information easily accessible. The universal raise in the  number  of  mobile  subscribers,  the  shift  to 
higher-data-rate  mobile  broadband  and  the increasing  contribution  of  information  technology leads  to  the  overall 
energy  consumption  of  the world.  Hence  there  is  a  need  on  environmental view  to  reduce  the  energy  requirements 
of  radio access  networks. Communication through a wireless channel is a challenging task since the medium introduces a 
lot of impairments.  Inspired by the green communication trend of the next generation wireless networks an energy-efficient 
cooperative wireless networks have been proposed in this work. The performance characteristics of the Decode  and Forward 
relaying  scheme  has  been analyzed  and  also  compared  with  the  direct relaying  scheme.  The energy efficiency metric 
of the two schemes have been analyzed and simulated via MATLAB.  Simulation results demonstrate that  the proposed 
scheme the energy efficient scheme significantly improve the energy efficiency compared to direct transmission scheme.
