QoS-aware User Load Management with Beamforming for Energy Efficiency in Wireless Networks

Abstract

Abstract-To overcome the congestion by load management of cell network, beam breathing based load management scheme is proposed to meet the issue. The proposed energy efficient load management scheme is based on beamforming layer breathing and multiple users handling of single beamforming transmission. The beam breathing is first handled by downlink beamforming transmission power control (breathe in or out) to manage the congestion. Subsequently, a single beam multi-users method for load balancing is discussed. Lastly, the linear equalizers Zero Forcing (ZF) and Minimum Mean Square Error (MMSE) with successive interference cancellation are exploited to recover information from multiplexed transmissions. The proposed scheme is effective to decrease the power consumption, congestion control, load balancing and is also constructive to increase the data rate in wireless communication. Simulation results reveal that the proposed work is quite better than the existing solutions in terms of throughput and energy consumption.Index Terms-Beamforming breathing, load balancing, congestion control, inter-cell interference, energy-efficient network.
