Cognitive radio: an enabling technology for the green radio communications concept

ABSTRACT

In this paper, Cognitive Radio (CR) is proposed as an efficient technology to meet the Green communications concept. First of all, the concept of "green communications" is extended to the radio communications world. The main topics, described for example in the call for papers of the first Greencom09 Workshop include energy-efficient network, protocols, devices and energy management. But to reduce the global CO₂ emission to protect our environment is not the sole way to address this green concept in wireless communications. The proper use and the optimal sharing of spectrum resources is also a very important topic. In this paper the electromagnetic waves can be considered as a pollution for other users and we shall also deal with this problem. Sustainable development should also address the human aspects both from the social and the health point of views. This paper demonstrates that CR may be a very good technology for dealing with the green radio communication, by describing in detail several examples.
