ABSTRACT
Next generation wireless networks (i.e., WiMAX, LTE) provide higher bandwidth and spectrum efficiency leveraging smaller (femto) cells with orthogonal frequency division multiple access (OFDMA). The uncoordinated, dense deployments of femtocells however, pose several unique challenges relating to interference and resource management in these networks. Towards addressing these challenges, we propose RADION, a distributed resource management framework that effectively manages interference across femtocells. RADION's core building blocks enable femtocells to opportunistically find the available resources in a completely distributed and efficient manner. Further, RADION's modular nature paves the way for different resource management solutions to be incorporated in the framework. We implement RADION on a real WiMAX femtocell testbed deployed in a typical indoor setting. We extensively evaluate two solutions integrated with RADION, both via prototype implementation and simulations and quantify their performance in terms of quick and efficient self-organization.

Subchannel allocation for the OFDMA-based femtocell system
In femtocell networks, due to their small cell size, we can achieve higher spatial diversity from the channel reuse between multiple femtocells. In addition, if femtocells operate on OFDMA systems, each subchannel can be reused separately among ...
Fairness Guaranteed Cooperative Resource Allocation in Femtocell Networks
User-deployed low-power femtocell access points (FAPs) can provide better indoor coverage and higher data rates than conventional cellular networks. However, a major problem in this uncoordinated frequency reuse scenario is the inter-cell interference. ...
Dynamic frequency allocation of femtocells for guaranteed macrocell throughput in OFDMA networks
ICUIMC '12: Proceedings of the 6th International Conference on Ubiquitous Information Management and CommunicationRecently, femtocells have been introduced for indoor coverage extension and higher bandwidth services. However, the frequency allocation problem between the femtocells and the macrocell causes co-channel interference to be treated carefully. In this ...
