本論文敘述一個無線感測網路的封包截取分析工具架構設計,針對目前市場硬體設備進行資訊的蒐集與比較,採用的Freescale MC1322x USB Sniffer Dongle,其外型輕巧,方便攜帶,價格也相對較低。本論文自行研究開發的軟體程式,將封包的格式由USB進行轉換為Libpcap的方式,解決Wireshark無法判別出Freescale USB Sniffer Dongle裝置的問題。因此,利用本論文所開發之軟體搭配開放原始碼Wireshark網路封包分析軟體,即可於桌上型電腦或筆記型電腦上,分析區域範圍內的IEEE802.15.4 ZigBee網路封包。
This thesis describes a packet analysis tool for wireless sensor networks. In order to focus on hardware equipment, we collect related information to analysis."Freescale USB Sniffer dongle" is a portable device which has lower price. We transform the format of USB into Libpcap such that the USB dongle could be adapted to a popular open-source application “Wireshark.” Therefore, the user can capture and analyze IEEE802.15.4 ZigBee packets just by a desktop/laptop, a dongle and Wireshark.
