Abstract
To be able to serve the traffic demand in today's mobile networks, more than 123.000 base stations (BSs) have been deployed by the different network providers in Germany. These BSs are working 24/7 and are dimensioned to serve capacity demand during busy hours. Currently no mechanisms for a load adaptive network reconfiguration are implemented. As a result, much energy is wasted during times in which the capacity demand is low. This paper describes an adaptive, context-aware, and technology-comprehensive system architecture for power management in modern radio networks. The results presented are developed within the project Communicate Green (ComGreen). A major goal of ComGreen is the development of a testbed in order to investigate and demonstrate the main achievements of the project. The aim of this paper is twofold: First, it highlights the ComGreen concepts for power management in heterogeneous radio networks. Second, a detailed description of the testbed is provided.
