This paper presents a framework that addresses Quality of Service (QoS) for industrial wireless sensor networks as a real-time measurable set of parameters within the context of feedback control, thereby facilitating QoS management. This framework is based on examining the interaction between the industrial control processes and the wireless network. Control theory is used to evaluate the impact of the control/communication interaction, providing a methodology for defining, measuring, and quantifying QoS requirements. An example is presented illustrating the wireless industrial sensor network (WISN) QoS management framework for providing dynamic QoS control within WISN. The example focuses on WISN operating in a time-varying RF interference environment in order to manage application-driven QoS latency constraints.
本文提出了一个框架，该框架将工业无线传感器网络的服务质量（QoS）作为反馈控制环境下一组可实时测量的参数来处理，从而便于进行QoS管理。此框架基于研究工业控制过程与无线网络之间的交互。控制理论用于评估控制/通信交互的影响，提供一种定义、测量和量化QoS要求的方法。给出了一个示例，说明了用于在无线工业传感器网络（WISN）内提供动态QoS控制的WISN QoS管理框架。该示例重点关注在时变射频干扰环境中运行的WISN，以管理应用驱动的QoS延迟约束。
