1、大連海事大學(xué)碩士學(xué)位論文無(wú)線傳感器網(wǎng)絡(luò)網(wǎng)關(guān)節(jié)點(diǎn)的設(shè)計(jì)實(shí)現(xiàn)姓名:鄒韜申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):信息與通信工程(通信與信息系統(tǒng))指導(dǎo)教師:王瑩20100601中文摘要摘要近年來(lái),無(wú)線傳感器網(wǎng)絡(luò)以其不可比擬的優(yōu)越性,已經(jīng)得到了國(guó)際上研究機(jī)構(gòu)的廣泛關(guān)注。無(wú)線傳感器網(wǎng)絡(luò)綜合了無(wú)線通信技術(shù)、傳感器技術(shù)、嵌入式技術(shù)、分布式信息處理技術(shù)等,能夠?qū)崟r(shí)采集監(jiān)測(cè)區(qū)域內(nèi)的信息,通過(guò)無(wú)線通信模塊將采集到的信息發(fā)送給匯聚節(jié)點(diǎn),以實(shí)現(xiàn)復(fù)雜環(huán)境下的目標(biāo)監(jiān)測(cè)。無(wú)線傳感器網(wǎng)絡(luò)已經(jīng)在軍事、工業(yè)、農(nóng)業(yè)、環(huán)境和醫(yī)療護(hù)理等領(lǐng)域得到了廣泛的應(yīng)用。無(wú)線傳感器網(wǎng)絡(luò)網(wǎng)關(guān)是網(wǎng)絡(luò)的控制中心,是實(shí)現(xiàn)無(wú)線傳感器網(wǎng)絡(luò)內(nèi)網(wǎng)與外網(wǎng)之間
2、通信重要網(wǎng)關(guān)。無(wú)線傳感器網(wǎng)絡(luò)網(wǎng)關(guān)實(shí)現(xiàn)了對(duì)監(jiān)測(cè)范圍內(nèi)的所有傳感器節(jié)點(diǎn)采集到的數(shù)據(jù)融合工作,負(fù)責(zé)將傳感器采集到的數(shù)據(jù)通過(guò)無(wú)線通信或者以太網(wǎng)發(fā)送給遠(yuǎn)程終端,同時(shí)對(duì)監(jiān)控中心所發(fā)的指令給予相應(yīng)處理。目前對(duì)無(wú)線傳感器的研究大多集中在傳感器節(jié)點(diǎn)之間的通信協(xié)議上,針對(duì)這種現(xiàn)狀,本文提出了一種基于嵌入式的無(wú)線傳感器網(wǎng)絡(luò)的網(wǎng)關(guān)節(jié)點(diǎn)的設(shè)計(jì)實(shí)現(xiàn)。本論文首先介紹了無(wú)線傳感器網(wǎng)絡(luò)的特點(diǎn)和應(yīng)用,以及目前無(wú)線傳感器網(wǎng)絡(luò)網(wǎng)關(guān)的發(fā)展?fàn)顩r,提出了基于嵌入式無(wú)線傳感器網(wǎng)絡(luò)網(wǎng)關(guān)的整體設(shè)計(jì)方案。在硬件上,網(wǎng)關(guān)選用基于ARM9內(nèi)核的32位低功耗控制器$3C2410作為硬件平臺(tái)的核心。軟件平臺(tái)采用Linux操作系統(tǒng)
