我们提供了一个分析框架，在无线传感器网络中的MAC协议的前导码采样技术，从中我们推导出封闭形式的生命周期和可靠性计算公式。除了考虑控制所发送的前导码的形式和内容的发送器行为之外，我们的模型还考虑了在成功接收和失败接收的情况下控制前导码接收的持续时间的接收器行为。沿着发射机和接收机的行为，我们的模型考虑了一个非完美的信道，从而考虑到传输错误和重传的生命周期和前导码采样协议的可靠性的影响。数值结果表明，没有协议是普遍最优的，也就是说，每个协议都有自己的最佳操作点，取决于给定的信道和负载条件。
We provide an analytical framework for preamble sampling techniques for MAC protocols in wireless sensor networks, from which we derive closed-form formulas for lifetime and reliability calculations. In addition to take into account transmitter behavior that controls the form and the content of the transmitted preamble, our model also considers receiver behavior that controls the duration of preamble reception in case of successful and failed reception. Along with both transmitter and receiver behavior, our model considers a non-perfect channel and thus takes into account the impacts of transmission errors and retransmissions on lifetime and reliability of preamble sampling protocols. Numerical results show that no protocol is universally optimal; that is, each protocol has its own optimal operation point that depends on the given channel and load conditions.
