就是由大量的密集部署在監(jiān)控區(qū)域的智能傳感器節(jié)點(diǎn)構(gòu)成的一種網(wǎng)絡(luò)應(yīng)用系統(tǒng)。 4． 指導(dǎo)教師審閱意見(jiàn) 該生根據(jù)畢業(yè)設(shè)計(jì)任務(wù)查詢了相關(guān)的資料，對(duì)課題相關(guān)的內(nèi)容有一定的了解；設(shè)計(jì)思路明確，設(shè)計(jì)方案合理，同意開(kāi)題 。 實(shí)現(xiàn)預(yù)期目標(biāo)的可行性分 析： 1. 熟悉 tinyos開(kāi)發(fā)環(huán)境； 2. 學(xué)習(xí)理解 CC2430搭建的節(jié)點(diǎn)電路，明白無(wú)線信道選擇的原理； 3. 學(xué)習(xí) nesC語(yǔ)言，深入理解 ZigBee協(xié)議棧源代碼，基本完成程序的大綱； 4. 調(diào)用 ZigBee協(xié)議棧完成無(wú)線信道選擇程序的編寫； 5. 完成程序的 調(diào)試，運(yùn)行。 2． 本課題需要重點(diǎn)研究的關(guān)鍵問(wèn)題、解決的思路及實(shí)現(xiàn)預(yù)期目標(biāo)的可行性分析 本課題重點(diǎn)研究的關(guān)鍵問(wèn)題：如何利用 nesC調(diào)用 ZigBee協(xié)議棧設(shè)置無(wú)線傳感器信道的選擇。隨著無(wú)線傳感器網(wǎng)絡(luò)應(yīng)用的日益發(fā)展和不斷深入，支持無(wú)線傳感器網(wǎng)絡(luò)的超微型操作系統(tǒng)的研究以及無(wú)線傳感器通信技術(shù)的研究，將
