9、網(wǎng)典型應(yīng)用場景和電信運(yùn)營商的應(yīng)用需求,提出了一個基于Zigbee/GPRS的物聯(lián)網(wǎng)網(wǎng)關(guān)系統(tǒng),實現(xiàn)了傳感網(wǎng)與電信網(wǎng)絡(luò)之間的數(shù)據(jù)傳送、不同類型感知網(wǎng)絡(luò)之間的協(xié)議轉(zhuǎn)換,以及對傳感器網(wǎng)絡(luò)的部分管理控制功能.最后,給出原型系統(tǒng)的實現(xiàn)技術(shù)和系統(tǒng)驗證.關(guān)鍵詞物聯(lián)網(wǎng);無線傳感網(wǎng)
