Multiuser Diversity Based Energy Efficiency Optimization for Heterogeneous Wireless Mobile Networks
Wireless communications knows a real progress that continues relentless as subscribers make use of new products and services using mobile devices offering more and more powerful feature sets and performance. Consequently we notice both a growth in electromagnetic radiation which can be harmful for human health, and mobile battery consumption that has to be increasingly greater with such performances. In this paper 1 we propose a new power optimization scheme that aims at reducing the transmit power at the mobile terminal side, based on channel gain diversity algorithm associated with two-power allocation schemes, The first one is a basic power allocation used to validate the cooperative approach, and the second one is based on game theory that aims at enhancing the performance compared to the first power allocation
