Cooperation based energy efficiency optimization using game theory framework for heterogeneous networks

Wireless communications knows a real progress that continues relentless as subscribers consume new products and services using mobile devices having more and more powerful feature sets and performance. Consequently we have both a growth in electromagnetic radiation which can be harmful for human health, and mobiles battery consumption that have to be increasingly greater with such performances. In this paper1 we propose a new power optimization scheme that aims to reduce the transmit power while guarantying a good capacity for the system, based on a cooperation protocol algorithm and using a game theory based resource allocation scheme.
