【正文】 很多的要求。新出的ZigBee Pro規(guī)范對網(wǎng)狀網(wǎng)絡(luò)的實(shí)現(xiàn)進(jìn)行了更好的定義，今后可以通過使用滿足ZigBee Pro規(guī)范的協(xié)議棧來實(shí)現(xiàn)網(wǎng)狀網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)，從而使系統(tǒng)有了更好的網(wǎng)絡(luò)自愈功能； (4)在今后更大更復(fù)雜的網(wǎng)絡(luò)中，網(wǎng)絡(luò)的同步也是一個值得注意的問題，我們可以通過使用信標(biāo)幀等方式來實(shí)現(xiàn)網(wǎng)絡(luò)同步要求，從而可以提高整個網(wǎng)絡(luò)的性能。 致 謝 感謝我的導(dǎo)師劉智老師。在劉智老師的諄諄教導(dǎo)下， 我的畢業(yè)設(shè)計(jì)及論文順利完成 。在由我不知道什么是ZigBee到完成整個ZigBee無線定位設(shè)計(jì)，是劉智導(dǎo)師給拉我學(xué)習(xí)的機(jī)會和幫助。同時感謝我的研究生學(xué)長張衛(wèi)東。在張衛(wèi)東學(xué)長的幫助下我克服啦重重困難，掌握了大量關(guān)于ZigBee方面的知識。 最后謝謝長春理工大學(xué)能給我一次在大學(xué)中發(fā)展的機(jī)會，走向社會也不會忘記我的母校——長春理工大學(xué)。 謝謝! 參考文獻(xiàn)[1] James , Steen , Julian , Karen Devereaux universal location services using a wireless E9location network[J].
