基于ARM的无线传感器网络MAC协议设计与实现

Design and implementation of MAC protocol for wireless sensor network based on ARM

针对无线传感器网络的特点,IEEE802.15.4标准以其低速率、低功耗、短距离等技术特征成为无线传感器网络底层协议栈的最佳选择之一。研究IEEE802.15.4介质访问控制(MAC)层协议栈后,在ARM9Linux平台上设计并实现IEEE802.15.4MAC层协议栈软件,软件最终以Linux字符型驱动的形式发布。结果表明,软件能完整实现IEEE802.15.4MAC层协议,具有较大的实用性和扩展性。

IEEE 802.15.4 standard has been one of the most suitable standards for the underlying protocol stack of Wireless Sensor Metwork （WSN） because of its low-rate,low power-consumption,and short-distance.An IEEE 802.15.4 Medium Access Control （MAC） layer protocol stack software was designed and implemented on ARM9 Linux platform after studying IEEE 802.15.4 MAC protocol stack.The software was released in the form of Linux character driver eventually.The results indicate that this software is of greater practicality and scalability.
