基于公平性的无线Mesh网络MAC层协议研究的中期报告摘要：无线Mesh网络是一种无线网状拓扑结构的网络，具有自组织、灵活、可靠等优点，已经成为了新一代无线网络的研究热点。在无线Mesh网络中，MAC层协议扮演着决定网络性能的关键角色。然而，现有的无线Mesh网络MAC层协议在保证网络吞吐量的同时忽略了网络中各节点的公平性问题，导致网络中一些节点的传输性能比其他节点弱，严重影响了网络的性能。因此，基于公平性考虑的无线Mesh网络MAC层协议研究成为了当前研究的焦点之一。本中期报告主要介绍了无线Mesh网络中MAC层协议的研究现状，重点探讨了基于公平性的无线Mesh网络MAC层协议的设计思想和实现方法。首先，介绍了无线Mesh网络MAC层协议中常用的跳频技术、时隙分配技术和载波感知技术。然后，阐述了现有的无线Mesh网络MAC层协议的特点和不足之处。接着，从公平性的角度出发，提出了基于最小传输时间的公平性无线Mesh网络MAC层协议的设计思想，并详细阐述了其实现方法。最后，对比了不同的无线Mesh网络MAC层协议的性能指标，证明了基于公平性考虑的MAC层协议相对于传统的MAC层协议具有更好的公平性和网络性能。关键词：无线Mesh网络，MAC层协议，公平性，最小传输时间Abstract:Wirelessmeshnetworksareatypeofwirelessmeshtopologynetworkwiththeadvantagesofself-organization,flexibilityandreliability.Theyhavebecomearesearchhotspotinthefieldofthenewgenerationofwirelessnetworks.Inawirelessmeshnetwork,theMAClayerprotocolplaysacriticalroleindeterminingnetworkperformance.However,existingwirelessmeshnetworkMAClayerprotocolsneglecttheissueoffairnessamongnodesinthenetworkwhileensuringnetworkthroughput,resultinginsomenodeshavingweakertransmissionperformancethanothers,severelyaffectingnetworkperformance.Therefore,researchonwirelessmeshnetworkMAClayerprotocolsbasedonfairnessconsiderationshasbecomeoneofthecurrentresearchfocalpoints.ThismidtermreportmainlyintroducestheresearchstatusoftheMAClayerprotocolinwirelessmeshnetworksandfocusesonthedesignideasandimplementationmethodsofwirelessmeshnetworkMAClayerprotocolsbasedonfairnessconsiderations.First,commonlyusedfrequencyhoppingtechniques,timeslotallocationtechniques,andcarriersensingtechniquesinwirelessmeshnetworkMAClayerprotocolsareintroduced.Then,thecharacteristicsandshortcomingsofexistingwirelessmeshnetworkMAClayerprotocolsareexplained.Fromtheperspectiveoffairness,thedesignideaofafairwirelessmeshnetworkMAClayerprotocolbasedontheminimumtransmissiontimeisproposed,anditsimplementationmethodisdetailed.Finally,performanceindicatorsofdifferentwirelessmeshnetworkMAClayerprotocolsarecompared,showingthatMAClayerprotocolsbasedonfairnessconsiderationshavebetterfairnessandn
