在无线传感器网络中，能量效率和通信可靠性往往是相互冲突的要求。此外，某些应用领域（如工业自动化或基础设施监控）会施加严格的延迟限制。低功耗接收器（<1mW功耗）与经过调整的MAC协议一起具有满足这些不同要求的潜力。我们提出了一个国家的最先进的低功耗接收机的概述，并将其特性与不同应用领域的要求。我们比较低功耗接收器占空比收发器和目前的应用程序依赖于他们。为此，我们使用功耗、灵敏度和数据速率作为低功耗接收器的关键性能指标。根据应用的特点，我们得出使用低功耗接收器，而不是占空比收发器的指导方针。
In wireless sensor networks (WSNs) energy efficiency and communication reliability are often conflicting requirements. Additionally, some application areas such as industrial automation or infrastructure monitoring impose strict latency bounds. Low-power receivers (< 1mW power consumption) together with adapted MAC protocols have the potential to meet these diverse requirements. We present an overview of state-of-the-art low-power receivers and relate their characteristics to requirements for different application areas. We compare low-power receivers to duty-cycled transceivers and present applications depending on them. For this, we use power consumption, sensitivity, and data rate as key performance figures for low-power receivers. Based on the characteristics of the applications we derive guidelines for using low-power receivers instead of duty-cycled transceivers.
