1.1 Standars
Wireless sensor standards have been developed with the key design requirement for low power consumption. The standard defines the functions and protocols necessary for sensor nodes to interface with a variety of networks.Someof these standardincludeIEEE802.15.4,ZigBee,WirelessHART,ISA100.11,IETF6LoW-PAN,IEEE802.15.3,Wibree.The follow-ing paragraphs describes these standards in more detail.
IEEE802.15.4:IEEE802.15.4[37] is the proposed stan-dard for low rate wireless personal area networks (LR-WPAN's).IEEE802.15.4 focuses on low cost of deployment,low complexity, and low power consumption.IEEE802.15.4 is designed for wireless sensor applications that require short range communication to maximize battery life. The standard allows the formation of the star and peer-to-peer topology for communication between net-work devices.Devices in the star topology communicate with a central controller while in the peer-to-peer topol-ogy ad hoc and self-configuring networks can be formed.IEEE802.15.4devices are designed t


1.1 標(biāo)準(zhǔn)
協(xié)議:無線傳感器標(biāo)準(zhǔn)已經(jīng)發(fā)展出關(guān)鍵的設(shè)計要求低功率消耗。這項(xiàng)標(biāo)準(zhǔn)定義了對于傳感器節(jié)點(diǎn)到不同網(wǎng)絡(luò)接口的必要功能和協(xié)議。這些標(biāo)準(zhǔn)中有些包括IEEE802.15.4,無線個域網(wǎng)技術(shù),IEEE802.15.3,短距離無線通信技術(shù)。以下段落更為詳細(xì)的描述了這些標(biāo)準(zhǔn)。
IEEE802.15.4:IEEE802.15.4是針對低速無線個域網(wǎng)制定的標(biāo)準(zhǔn),針對低成本,低復(fù)雜度,低功耗。IEEE802.15.4是為無線傳感器應(yīng)用制定的,要求在小范圍內(nèi)實(shí)現(xiàn)電池壽命的最大化。這項(xiàng)標(biāo)準(zhǔn)支持基于星型和對等網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)的網(wǎng)絡(luò)設(shè)備間的通信,設(shè)備在星拓?fù)渑c中央控制器的通信在對等網(wǎng)絡(luò)拓?fù)涮卦O(shè)和自我設(shè)置的網(wǎng)絡(luò)可以形成?;贗EEE802.15.4標(biāo)準(zhǔn)設(shè)計的設(shè)備支持物理層和數(shù)據(jù)鏈路層協(xié)議。物理層支持865/915 MHZ低帶寬和2.4GHZ高帶寬。數(shù)據(jù)鏈路層使用載波偵聽沖突檢測機(jī)制控制訪問無線網(wǎng)絡(luò)。數(shù)據(jù)鏈路層也負(fù)責(zé)數(shù)據(jù)幀的驗(yàn)證,幀傳輸,網(wǎng)絡(luò)接口,網(wǎng)絡(luò)同步,設(shè)備兼容,保護(hù)設(shè)備。使用IEEE802.15.4協(xié)議的無線傳感器應(yīng)用包括民用住宅,工業(yè),環(huán)境監(jiān)測,控制自動化。Zigbee基于IEEE802.15.4低速無線個域網(wǎng)的標(biāo)準(zhǔn)定義了高層通信協(xié)議,Zigbee技術(shù)是一項(xiàng)簡單,低成本,低功率,嵌入式應(yīng)用方面的無線通信技術(shù),Zigbee設(shè)備可以可以
