A Simulation Framework for the Evaluation of Scenarios and Algorithms for Common Radio Resource Management
We present a simulation framework based on a systematic view on Common Radio Resource Management (CRRM). It enables a cost-benefit investigation of different CRRM algorithms and architectures. Different scenarios, centralized as well as decentralized ones, can be clearly defined based on five standard components, namely the radio access system, the environment, the user equipment, the CRRM information manager, and the CRRM decider. The costs and time consumption of CRRM operations are taken into account via chargeable messages. The clarity of the model enables an efficient investigation of CRRM algorithms based on optimization theory, game theory, physical models and other methods. The resulting framework has been implemented as a hybrid simulation model using OMNeT++. A convenient and straightforward integration of different wireless network technologies and user service demands is also supported; models for UMTS and GSM/EGPRS are already integrated. The scope of the proposed framework is demonstrated by the evaluation of realistic scenarios.
