　　無線傳感器網絡WSN（Wireless Sensor Network）是由部署在監測區域內大量的具有信息采集、數據處理和無線通信能力的微小傳感器節點通過無線電通信形成的一個多跳的自組織網絡系統，其目的是協作地感知、采集和處理網絡覆蓋區域里被監測對象的信息，并發送給觀測者^[1]。
　　無線傳感器網絡可被廣泛應用于軍事、環境保護、醫療護理、智能家居、智能交通、智能建筑、工業控制和監視^[2]、空間探測^[3]等領域。
　　目前國內外出現了多種無線傳感器網絡節點的硬件平臺。典型的節點^[4]包括Mica系列、Telos、IRIS和Imote2等。各平臺的主要區別是采用了不同的處理器和無線通信模塊。有些節點具有高性能，但功耗較大，如Imote2節點，不適用于能量受限的應用環境。其他一些節點，如Telos、Mica等，由于設計時間較早，其性能已經落后于當今的集成電路工業設計水平。因為無線傳感器網絡節點一般采用電池供電，工作環境通常比較惡劣，而且數量大、更換非常困難，所以低功耗是無線傳感器網絡最重要的設計準則之一^[5]。本文節點的硬件設計綜合考慮了功耗和性能，實現了配備無線收發模塊、微控制器模塊、電源模塊和I/O擴展接口的無線傳感器網絡節點。相比現有節點，該節點功耗更低、性能更優。TinyOS是適用在無線傳感器網絡應用的嵌入式實時操作系統，然而其無法很好地在新的硬件平臺提供對TinyOS的支持，這成為限制其應用的主要瓶頸之一。本文改進了TinyOS的工具鏈環境，使得操作系統移植和軟件開發工作可以擺脫GCC的限制，進而使得TinyOS可以應用于更廣泛的硬件環境。本文基于改進的工具鏈環境，將TinyOS 2.1.0版本移植到新的節點上，并且為節點所使用的CC2520無線收發芯片編寫了驅動程序(在TinyOS語言中，稱之為射頻協議棧Radio Stack)。
1 硬件設計
　　無線傳感器網絡節點是網絡的基本單元，節點的穩定運行是整個網絡可靠性的重要保障。在不同的應用中，傳感器網絡節點的組成不盡相同。已有的節點，有的只考慮低功耗而性能不高，有的性能高但是功耗太大。本文所設計的節點配備了基本的無線收發模塊、微控制器模塊、電源模塊和I/O擴展接口。該節點的硬件設計綜合考慮了功耗和性能等諸多方面，較之現在主流節點(如telosB、micaz等)，本文設計的節點采用了功耗更低的處理器芯片和性能更好的射頻收發器芯片。
　　處理器和無線收發模塊是節點的兩個關鍵模塊，本文所設計的節點選擇了超低功耗處理器MSP430F2618和工作在ISM自由頻段的射頻芯片CC2520。處理器模塊是數據處理、進程調度的核心單元，一般由MCU和擴展的存儲器組成。根據WSN的低功耗要求，MCU芯片的選擇標準包括：工作模式、工作電流、工作電壓、喚醒時間等。無線通信模塊是WSN 組網以及WSN與信息世界相連接的重要模塊，一般由無線收發芯片和相應頻率的天線組成。由于WSN 的無線通信傾向于無線電通信，所以選用工作在ISM 自由頻段的射頻芯片。本文設計的節點電路示意圖如圖1所示。
