Multi-objective Power Control Algorithm for Femtocell Networks

摘要

Future wireless networks are designed to cope with drastically increasing user demands. However, network resources reach the limits of their capacity to user requirements. Recently, femtocell has appeared as an effective solution to achieve larger coverage for indoor users while improving the cellular network capacity. In femtocell networks, the most important issue is to design an efficient and fair power control protocol, which can significantly influences the network performance. In this paper, a new multi-objective power control algorithm is developed based on the no-regret learning technique and intervention game model. The proposed control paradigm can provide the ability to practically respond to current system conditions and suitable for real network operations. Under a dynamically changing network environment, the proposed approach appropriately controls the power level to balance network performance between efficiency and fairness.
