Throughput Maximization Based on User Association in Heterogeneous Networks

Cellular networks' endurance limitations are in constant abatement as extra numbers of cellular phone users are persistently occupying the resources of the network. Consequently, network resources, signal quality, Quality of Service (QoS) requirements etc. undergo hazardous conditions. Moreover, edge users are also endangered as they experience poor signal quality due to large separation distance and obstacles. However, smaller cells were introduced to alleviate the burdens from networks and explicitly comfort users. This paper, studies the Femto-cells performance over cellular networks and further proposes a user association scheme to off-load users to the Femto-cells. The simulation results reflect the outstanding performance of Femto-cells capabilities and how deploying 5 Femto-cells can relatively add-up 3Mbps to each user's throughput and approximately 10Mbps in a single iteration.
