Abstract :
Currently, the majority of mobile subscribers rely on second-generation mobile technologies, but service providers are investing into aggressive rollouts of mobile broadband networks to deliver a fully-featured wireless Internet. While the main focus in research has been put on enhancing the capacity of this kind of networks, very little has been done regarding their energy efficiency. Assuming the worst-case design that is typically used in these networks, presented are the benefits, in terms of energy consumption reduction, of a network management approach in which some of the base stations serving a particular area are switched off. Theoretical as well as real traffic models are used for the evaluation.
