A Particle Swarm Optimization Algorithm for Resource Allocation in Femtocell Networks
Femtocell network is an efficient configuration to improve coverage and Quality of Service (QoS) in cellular networks. However, due to dense deployment, users in a femtocell may be interfered by the base stations nearby, resulting in a deteriorated throughput of the femtocell. In this paper, the authors investigate the resource allocation problem targeting at maxmin throughput of the femtocells. Under the assumption that a number of discrete power levels are available for each device, a joint optimization problem over power control and channel allocation is formulated. They show its hardness and propose a particle swarm optimization based algorithm PCASO.
