Fairness-Energy-Throughput Optimized Trade-off in Wireless Networks
Résumé
Increase the spectral efficiency and guarantee high Quality of Service (QoS) and high Quality of Experience (QoE) is the crucial issue of wireless communications. The best acknowledged opportunistic resource allocation schedulers allow to reach these objectives taking into consideration the radio conditions and users requirement in the allocation process. However, this is often process at the expense of energy efficiency which is now essential regarding the alarming greenhouse gas emission and the need to improve the device battery lifetime. This paper proposes an optimized trade-off between energy, throughput and fairness thanks to a new opportunistic approach that combines the advantages without the drawbacks of specialized schedulers. Performance evaluations show that the proposed solution allows to have the same system capacity that MaxSNR scheduler while solving its lack of fairness concerning mobiles at different distances from the access point. In addition we also show that this can be made lowering energy consumption.
