1、中文摘要摘要無線傳感器網(wǎng)絡(luò)是一種特殊的Ad.Hoe網(wǎng)絡(luò),它具有自組織、快速展開、抗毀壞性強(qiáng)等特點(diǎn),在軍事、環(huán)境監(jiān)測、醫(yī)療健康、工業(yè)控制等方面有著十分廣闊的應(yīng)用前景。近年來,隨著無線通信、集成電路、傳感器及微電機(jī)系統(tǒng)(MEMs)等技術(shù)的發(fā)展,使得大規(guī)模生產(chǎn)體積小、成本低、具有數(shù)據(jù)收集、短距離無線通信和數(shù)據(jù)處理能力的傳感器節(jié)點(diǎn)成為可能。技術(shù)條件的成熟和大量潛在的應(yīng)用需求使得無線傳感器網(wǎng)絡(luò)受到人們越來越多的關(guān)注和重視。無線傳感器網(wǎng)絡(luò)正成為國內(nèi)外無線網(wǎng)絡(luò)研究的一個(gè)熱點(diǎn)。本文主要研究無線傳感器網(wǎng)絡(luò)的設(shè)計(jì)及產(chǎn)品開發(fā)。無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)數(shù)量
2、龐大、單個(gè)節(jié)點(diǎn)資源極其有限,網(wǎng)絡(luò)設(shè)計(jì)的首要目標(biāo)是有效節(jié)約能源,延長網(wǎng)絡(luò)生命周期,并考慮網(wǎng)絡(luò)的連通性。本文取得主要成果如下:(1)無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)設(shè)備及產(chǎn)品開發(fā)文中以FreⅪscale的MCl3192無線收發(fā)器及MC9S08GT60微控制器為基礎(chǔ)成功得開發(fā)出通用的無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)設(shè)備,采用印刷線路技術(shù)研制出平面接收天線。整個(gè)無線傳感器節(jié)點(diǎn)體積小,結(jié)構(gòu)合理,成本低,能夠滿足企業(yè)客戶的要求。(2)IEEE802.15.4協(xié)議分析及軟件開發(fā)深入研究了IEEE802.15.4網(wǎng)絡(luò)協(xié)議棧(包括物理層,MAC子層)、MC9S08GT60
3、芯片的性能及指令系統(tǒng),開發(fā)出與網(wǎng)絡(luò)節(jié)點(diǎn)相應(yīng)的軟件。根據(jù)客戶對產(chǎn)品數(shù)據(jù)傳輸頻率要求低的特點(diǎn),利用網(wǎng)絡(luò)節(jié)點(diǎn)的休眠模式,使節(jié)點(diǎn)大部分時(shí)間處于休眠狀態(tài),有效地降低了節(jié)點(diǎn)的能耗。(3)WSN.AODV路由協(xié)議深入分析了AODV協(xié)議路由的建立過程及其在低功耗網(wǎng)絡(luò)中的應(yīng)用,針對LoWPAN等AODV協(xié)議的不足,提出了一個(gè)新的路由協(xié)議WSN-AODV。試驗(yàn)表明,特別是網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)經(jīng)常變化時(shí),在能量消耗,魯棒性和數(shù)據(jù)傳輸延遲等方面,WSN_AODV優(yōu)于現(xiàn)有的LoWPAN路由協(xié)議。關(guān)鍵詞:無線傳感器網(wǎng)絡(luò),IEEE802.15.4,AODV,WSN
