Title:QoE-awareEnergy-efficientWirelessResourceAllocationAlgorithminLTE-ASystems
Abstract:
Withtheincreasingdemandforhigh-qualityservicesandtherapidgrowthofdatatrafficinLTE-A(Long-TermEvolutionAdvanced)systems,resourceallocationplaysavitalroleinensuringbothqualityofexperience(QoE)andenergyefficiency.ThispaperpresentsanovelQoE-awareenergy-efficientwirelessresourceallocationalgorithmforLTE-Asystems.TheproposedalgorithmaimstooptimallyallocatewirelessresourcesconsideringQoErequirementswhileaimingtominimizeenergyconsumption.Thealgorithmtakesintoaccountvariousfactorssuchasuserpriority,channelcondition,andtrafficloadtomakeefficientallocationdecisions.SimulationresultsdemonstratethesuperiorityoftheproposedalgorithmintermsofQoEperformanceandenergyefficiencycomparedtoexistingresourceallocationtechniques.
