| dc.description.abstract | Fourth generation cellular networks provide ubiquitous broadband access to a growing number of mobile users worldwide. In this context, resource allocation in orthogonal frequency division multiple access femtocell network systems presents an important milestone towards realization of high-speed services. In this paper, we focus on impact of mobility dynamics on time/frequency allocation in femtocell network. We considered users’ mobility dynamics taking into account the variation of their positions with time. We propose a scalable mobility-aware femtocell cluster-based resource allocation (M-FCRA) scheme based on cluster formation, clusterhead resource allocation with user mobility awareness, and resource contention resolution. M-FCRA formulates the frequency/time resources allocation mathematically as a min–max optimization problem and generates synchronized resource reservation requests that maximize bandwidth utilization and quality of service. The results show that M-FCRA performs better than femtocell clusterbased resource allocation (FCRA) algorithm at various signal to interference and noise ratio levels in terms of throughput satisfaction rate and spectrum spatial reuse. | en_US |
