About

BeGREEN D2.3 provides evaluation and benchmarking, using simulation techniques, of the energy-saving mechanisms studied in BeGREEN. An end-to-end (E2E) system-level software simulator has been developed, so that the different energy-efficiency mechanisms in various parts of the network can be tested simultaneously, and in interaction with each other. The term ‘system-level’ means that all important network components are simulated, but for those at the link level (especially for radio links), approximations are used.
The simulator was used to emulate cellular deployments utilizing the different architectures studied so far in BeGREEN, while implementing the different mechanisms. In this way, the forecasts on how real systems with the proposed novel mechanisms behave are obtained. This will enable us to predict the energy efficiency levels that can be achieved. Several energy-saving-focused experiments were carried out and their findings are reported.
