1、鄭州大學(xué)碩士學(xué)位論文AdHoc網(wǎng)絡(luò)路由協(xié)議的設(shè)計(jì)與仿真姓名:程鳳娟申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):計(jì)算機(jī)軟件與理論指導(dǎo)教師:周清雷20070518鄭州人學(xué)碩I:學(xué)位論史摘要無(wú)線移動(dòng)自組網(wǎng)(AdHoe)是一種特殊的無(wú)線移動(dòng)通信網(wǎng)絡(luò),網(wǎng)絡(luò)中的所有移動(dòng)終端地位平等、自組織、無(wú)需事先布置任何網(wǎng)絡(luò)設(shè)施或中心控制節(jié)點(diǎn),具有網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)動(dòng)態(tài)變化、網(wǎng)絡(luò)帶寬與能量受限等特點(diǎn)。無(wú)線移動(dòng)自組網(wǎng)成為近幾年研究熱點(diǎn),對(duì)其媒體接入控制和路由協(xié)議的研究存在著巨大的挑戰(zhàn)。本文研究了AdHoe網(wǎng)絡(luò)路由協(xié)議與技術(shù),重點(diǎn)討論了幾種典型的路由協(xié)議:AoDv(AdHoeOn—demandDistanceVectorRouting
2、,AdHoe按需距離向量協(xié)議)、DSR(DynamicSourceRoutingProtocol,動(dòng)態(tài)源路由協(xié)議)、DSDV(DestinationSequencedDistanceVector,目的節(jié)點(diǎn)排序距離向量路由協(xié)議)和TORA(TemporaryOrderedRoutingAlgorithm,臨時(shí)排序路由算法),深入研究了上述路由協(xié)議算法。針對(duì)不同網(wǎng)絡(luò)模式、不同移動(dòng)場(chǎng)景和不同的傳輸負(fù)載對(duì)以上路由協(xié)議進(jìn)行了模擬,選取延遲、包投遞率、路由開(kāi)銷、網(wǎng)絡(luò)系統(tǒng)生存時(shí)間作為參數(shù),在網(wǎng)絡(luò)仿真平臺(tái)NS2上進(jìn)行了協(xié)議仿真,對(duì)仿真結(jié)果進(jìn)行了詳盡的分析,分析結(jié)果對(duì)AdHoc網(wǎng)絡(luò)工程應(yīng)用、網(wǎng)絡(luò)部
3、署具有現(xiàn)實(shí)的指導(dǎo)意義。本文還針對(duì)AdHoc網(wǎng)絡(luò)中能量受限的特點(diǎn),研究了基于能量保護(hù)的路山協(xié)議,給出了一種基于能量有效的路由協(xié)議EERP(EnergyEfficientRoutingProtoc01),定義了延遲公式,從而有效延長(zhǎng)網(wǎng)絡(luò)系統(tǒng)生存時(shí)間。通過(guò)在NS2上仿真測(cè)試,EERP較AODV具有更好的系統(tǒng)生存時(shí)間,驗(yàn)證了設(shè)計(jì)思想,為進(jìn)一步研究AdHoe網(wǎng)絡(luò)提供了參考和借鑒。關(guān)鍵字:移動(dòng)自組網(wǎng);路由協(xié)議;網(wǎng)絡(luò)模擬;NS2第11i(鄭州人學(xué)顧I:學(xué)位論文AbstractTheWirelessMobileAdHoeNetwork(WMANET)isaspecialwirelessmobil
