1、北京郵電大學世紀學院畢業(yè)設(shè)計(論文)題目無線Mesh網(wǎng)絡(luò)SMRPA安全路由協(xié)議分析學生姓名學號07020323所在系(院)通信與信息工程系專業(yè)名稱信息工程年級07級指導教師職稱副教授2010年5月15日摘要無線Mesh網(wǎng)絡(luò)(WirelessMeshNetwork,WMN),作為一種新型的無線通信網(wǎng)絡(luò),有著自組織性、自愈性、頻譜效率高、覆蓋范圍大、可擴展性強、可靠性強等眾多優(yōu)勢,能在更大的覆蓋范圍內(nèi)提供高的速率,成為下一代無線通信網(wǎng)絡(luò)研宂的熱點之一.但是WMN容易受到安全攻擊,比如受到竊聽、偽造、拒絕服務(wù)等,其安全目標與傳統(tǒng)有線網(wǎng)絡(luò)中的安全S標是一致的:可用性、機密性、完整性、安全認證和抗抵
2、賴性.Mesh路由協(xié)議基木沿用Adhoc網(wǎng)絡(luò)路由協(xié)議,但需要針對WMN的特點設(shè)計專門適用于WMN的安全、高效路由協(xié)議.SMRPA協(xié)議的基本思想是在路由建立之前先進行鄰節(jié)點認證,以免在路由建立過程屮有未授權(quán)節(jié)點加入到路由路徑屮。在路由建立過程屮,通過加密和Hash函數(shù)認證,確保收到的路由請求包的正確性和完整性,在S標節(jié)點選擇路由過程中遵循相應(yīng)數(shù)學原理合理選擇路徑數(shù)目并作出及時正確的路由響應(yīng)。數(shù)據(jù)通過節(jié)點分離的多條路徑傳輸時,能夠有效地利用網(wǎng)絡(luò)資源,減少網(wǎng)絡(luò)擁塞,降低時延、提高錯誤容忍性,減低丟包率,達到穩(wěn)定可靠的通信質(zhì)量。關(guān)鍵詞:無線Mesh網(wǎng)路由協(xié)議SMRPA安全路由協(xié)議TitleWire
