Title:AModifiedNSGA-II-basedoptimizationfordesigningproximity-awarecommunicationnetworks
Abstract:
Theproximity-awarecommunicationnetworkdesignproblemisachallengingtaskinthefieldofwirelesscommunication.Inthispaper,wepresentanovelapproachthatimprovestheperformanceoftheclassicalNSGA-IIalgorithmforsolvingthisoptimizationproblem.Theproposedapproachutilizestheconceptofproximityawarenesstoenhancetheefficiencyandqualityofserviceincommunicationnetworks.WeconductexperimentstoevaluatetheperformanceofthemodifiedNSGA-IIalgorithm,andtheresultsdemonstrateitssuperiorityoverthetraditionalNSGA-IIapproachbyachievinghighernetworkefficiencyandlowercommunicationlatency.
1.Introduction:
Inrecentyears,thedemandforefficientandreliablecommunicationnetworkshassignificantlyincreased.Proximity-awarecommunicationnetworkdesignplaysacrucialroleinmeetingthesedemandsbyoptimizingnetworktopology,minimizingcommunicationlatency,andmaximizingnetworkthroughput.Traditionaloptimizationalgorithmsmaystruggletoaddressthecomplexityofthisproblemduetothelargesearchspaceandnon-linearnatureoftheobjectivefunctions.Therefore,theapplicationofmetaheuristicalgorithms,suchasNSGA-II,isasuitablechoiceforsolvingthisoptimizationproblem.
