Conclusions and Future Works

Abstract

In this book, we investigate resource allocation and interference management in femtocell networks. A subchannel allocation algorithm based on the ant colony optimization is proposed in dense deployed femtocells. To explore the multi-dimensional diversity in resource allocation, we propose a semi-distributed interference-aware resource allocation algorithm for the uplink of co-channel deployed femtocells, based on a non-cooperative game framework. Furthermore, a joint subchannel and power allocation scheme for spectrum-sharing femtocells is investigated taking heterogeneous femto-user QoS requirements and a cross-tier interference limit into account. In Chap. 5, we have proposed an energy-aware uplink power control scheme for two-tier femtocell networks based on non-cooperative game. In Chap. 6, we have proposed a differentiated-pricing based power allocation algorithm for the uplink frequency-sharing femtocells, based on the non-cooperative game framework.
