基于T i n y O S 的無線傳感器網絡體系結構
無線傳感器網絡WSN(Wireless Sensor Network) 由部署在監測區域內大量廉價的傳感器節點組成,通過
無線通信方式形成multi2hop 自組織的網絡系統,其目的是協作地感知、采集和處理網絡覆蓋區域中感知
對象的信息,并發送給觀察者。本文從分析無線傳感器節點Mica 和其上運行的操作系統TinyOS 出發,
著重描述無線傳感器網絡節點應用程序體系結構和消息通信機制。
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.
