1、合肥工業(yè)大學(xué)碩士學(xué)位論文無(wú)線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)設(shè)計(jì)的研究姓名：黃長(zhǎng)喜申請(qǐng)學(xué)位級(jí)別：碩士專業(yè)：控制理論與控制工程指導(dǎo)教師：張崇巍20060801無(wú)線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)設(shè)計(jì)的研究摘要隨著社會(huì)發(fā)展的需求和通信技術(shù)、嵌入式系統(tǒng)和傳感器技術(shù)的進(jìn)展，具有感知、計(jì)算和無(wú)線通信能力的無(wú)線傳感器網(wǎng)絡(luò)(WSN)引起了人們的極大關(guān)注。本文以設(shè)計(jì)無(wú)線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)為目的，對(duì)無(wú)線傳感器網(wǎng)絡(luò)的起源和發(fā)展、研究現(xiàn)狀，以及幾項(xiàng)關(guān)鍵技術(shù)進(jìn)行了深入的了解，探討了無(wú)線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)研制的基本原則和思想。筆者認(rèn)為低能耗、可擴(kuò)展性與靈活性是一個(gè)WSN系統(tǒng)成功的關(guān)鍵，實(shí)現(xiàn)

2、這些要求需要在節(jié)點(diǎn)硬軟件、系統(tǒng)結(jié)構(gòu)和運(yùn)行策略上進(jìn)行深入的探討和周密的細(xì)節(jié)設(shè)計(jì)。論文工作中采用8位低功耗MCU芯片ATmegal28和射頻芯片CCl000進(jìn)行了一款無(wú)線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)的結(jié)構(gòu)與原理設(shè)計(jì)。研究支持開放源代碼的TinyOS操作系統(tǒng)移植的嵌入式設(shè)計(jì)，重點(diǎn)研究其低功耗機(jī)制。論文工作中對(duì)無(wú)線傳感器網(wǎng)絡(luò)的時(shí)間同步技術(shù)做了一些研究，在節(jié)點(diǎn)設(shè)計(jì)中實(shí)現(xiàn)了TPSN算法。在一個(gè)軟硬件試驗(yàn)平臺(tái)上對(duì)兩節(jié)點(diǎn)之間的TPSN時(shí)間同步算法進(jìn)行測(cè)試，試驗(yàn)結(jié)果說(shuō)明了設(shè)計(jì)的有效性。論文工作是對(duì)新型WSN的一個(gè)嘗試，為進(jìn)一步工作打下了基礎(chǔ)。關(guān)鍵詞：無(wú)
