移动AdHoc网络拥塞控制算法研究的中期报告

一、研究背景

Withtheincreasingnumberofmobiledevicesandwirelessapplications,MobileAdhocNetworks(MANETs)havebecomeanimportantresearcharea.MANETsconsistofacollectionofmobilenodesthatcommunicatewitheachotherthroughwirelesslinks.Thesenetworksarecharacterizedbytheirdynamictopology,limitedbandwidth,andoftenunreliablelinks.Duetotheinherentmobilityofthenodes,traditionalcongestioncontrolalgorithms,suchasthoseusedinwirednetworks,arenotsuitableforMANETs.Moreover,intheabsenceofacentralizedcontrol,itisdifficulttomonitorandmanagethetrafficinsuchnetworks.Therefore,efficientcongestioncontrolmechanismsarerequiredtoensurethatthenetworkoperatessmoothlyandthatthequalityofservice(QoS)requirementsoftheapplicationsaremet.

二、研究目的

Thegoalofthisresearchistoproposeacongestioncontrolalgorithmformobileadhocnetworksthatcanefficientlymanagethenetworktrafficandimprovetheoverallnetworkperformance.Theproposedalgorithmshouldbeabletoadapttothedynamictopologyofthenetwork,handlethevaryingtrafficload,andensurethatthenodeshaveafairshareoftheavailablebandwidth.Moreover,thealgorithmshouldbelightweight,soastominimizetheoverheadonthenetworkandtoconservethelimitedenergyresourcesofthenodes.

三、研究方法

Inthisresearch,wewillanalyzetheexistingcongestioncontrolalgorithmsforMANETsandidentifytheirstrengthsandweaknesses.Basedonouranalysis,wewillproposeanewalgorithmthataddressestheshortcomingsoftheexistingalgorithmsandmeetsourrequirements.Wewillusesimulationtools,suchasNS-3,toevaluatetheperformanceoftheproposedalgorithmundervariousscenarios,suchasdifferentnetworktopologies,trafficloads,andmobilitypatterns.Wewillcomparetheperformanceofouralgorithmwiththatofexistingalgorithms,anddemonstrateitssuperiority.
