For the purpose of the ComGreen  project, a test environment consisting of several components has been developed to visualize the effects of energy management algorithms for mobile networks under realistic conditions. This test environment comprises a multi radio access technology (Multi-RAT) testbed, which is a professional testbed suite consisting of a number of different radio access technology nodes. The second component is a showtable that demonstrates an energy management scenario based on contextual information gathered from network components as well as mobile devices. These contextual parameters are collected, evaluated and delivered to the algorithms by the Context Manager.
The scenario demonstrated by the Showtable uses WiFi access points and focuses on the deactivation and reactivation of unused network components and the intelligent handover of the active users. As an exemplary application, video streams are used to visualize the status of the network on an external screen and to display real-time information about traffic load and power consumption. The deployed algorithm is a threshold-based policy, which switches off one of the access points in case that aggregated traffic load of both access points is below a defined threshold. At the same time, the energy management algorithms guarantee a consistently high quality of experience perceived by the user.
