基于T i n y O S 的無線傳感器網(wǎng)絡(luò)體系結(jié)構(gòu)
無線傳感器網(wǎng)絡(luò)WSN(Wireless Sensor Network) 由部署在監(jiān)測區(qū)域內(nèi)大量廉價(jià)的傳感器節(jié)點(diǎn)組成,通過
無線通信方式形成multi2hop 自組織的網(wǎng)絡(luò)系統(tǒng),其目的是協(xié)作地感知、采集和處理網(wǎng)絡(luò)覆蓋區(qū)域中感知
對象的信息,并發(fā)送給觀察者。本文從分析無線傳感器節(jié)點(diǎn)Mica 和其上運(yùn)行的操作系統(tǒng)TinyOS 出發(fā),
著重描述無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)應(yīng)用程序體系結(jié)構(gòu)和消息通信機(jī)制。
Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks.
