2. Different approaches

Following previous concerns about energy consumption in mobile networks and their economic and environmental consequences, various scientific teams around the world are trying to find effective solutions to reduce energy consumption in mobile networks.

• The main avenues for improving the energy efficiency of wireless networks, currently being explored by research, are as follows:

  • improvement of the components used (always according to the energy criterion) ;

  • new generations of access points and base stations ;

  • optimization of the transmission link and radio resource management (RRM);

  • design of new control mechanisms and cooperation between BSs to achieve energy savings in the access network (RAN);...
