1、一種基于無(wú)線傳感器網(wǎng)絡(luò)的安全優(yōu)先門限敏感分簇路由協(xié)議鄭偉，蘇川，李開成(北京交通人學(xué)，軌道交通運(yùn)行控制系統(tǒng)國(guó)家工程研究中心，北京，100044)摘要：為構(gòu)建基于無(wú)線傳感器網(wǎng)絡(luò)的鐵路防災(zāi)安全監(jiān)控系統(tǒng)，在門限敏感的節(jié)能型網(wǎng)絡(luò)協(xié)議(TEEN)基礎(chǔ)上，提出1種安全優(yōu)先門限敏感分簇路山協(xié)議(SPTC)o確定SPTC的網(wǎng)絡(luò)架構(gòu)，基于能量計(jì)算公式設(shè)計(jì)簇頭分布算法及簇頭和副簇頭選舉算法，以及路由建立步驟和數(shù)據(jù)采集流程。在協(xié)議中定義副簇頭,保證數(shù)據(jù)路山的可靠性及數(shù)據(jù)自身傳輸?shù)陌踩?提高協(xié)議的安全性;在匯聚節(jié)點(diǎn)(SN)附近區(qū)域布置更小規(guī)模的簇，在兼顧剩余能雖與節(jié)點(diǎn)距離的準(zhǔn)則下選擇最佳的簇
2、頭節(jié)點(diǎn)，以提高協(xié)議的節(jié)能性。采用OMNeT++網(wǎng)絡(luò)仿真工具對(duì)SPTC進(jìn)行了建模仿真。仿真結(jié)果表明：當(dāng)網(wǎng)絡(luò)工作了10000s時(shí)，低能量節(jié)點(diǎn)數(shù)量比低功耗自適應(yīng)聚類層次協(xié)議(LEACH)減少了60%；當(dāng)災(zāi)害數(shù)據(jù)采集概率為0.5%時(shí)，基于SPTC協(xié)議的網(wǎng)絡(luò)檢測(cè)周期是基于LEACH的1.7倍。關(guān)鍵詞：無(wú)線傳感器網(wǎng)絡(luò)；防災(zāi)安全監(jiān)控系統(tǒng)；安全優(yōu)先；門限敏感；分簇路山協(xié)議AtypeofSafety?PriorityThresholdSensitiveClusteringRoutingProtocolBasedontheWirelessSensorNetworkZHENGWei,SUC
