摘　　要：能效是无线传感器网络各种协议的重要指标。为考察基于TinyOS2．X系统的ARQ差错控制协议模块的能效，利用IRIS节点进行了不同载荷和距离下的数据通信实验，统计获得了WSN通信过程中错误分布和误码特征，并系统地分析比较了几种ARQ差错控制的能效。结果表明，TinyOS2．X默认的无差错控制模式下传输可靠性低，一次重传的ARQ能有效提高可靠性，并取得较高能效。Energy efficiency is one of the most important target of WSN. In order to investi- gate the energy efficiency of ARQ error control scheme in TinyOS2. x, use IRIS entity nodes to experiment data communication under variable payload and distance, and obtain the char- acteristics of error and its distribution Also, have analyzed the energy efficiency of several error control methods systematically. The results show that the transport without error control is unreliable, which is the default mode of TinyOS2. x; contrarily, once-retry ARQ could enhance reliability and keep higher energy efficiency.
