本文介绍了一种名为 AirTight 的关键无线通信新协议的动机、设计、分析和实现。无线通信已成为许多网络物理应用基础设施的重要组成部分。这些应用程序中有许多是实时的，也是混合关键性的，因为它们具有具有不同故障后果的组件/子系统。无线通信不可避免地会受到一定程度的外部干扰。在本文中，我们使用关键性感知故障模型来表示这种干扰；对于故障模型中的每个干扰级别，我们保证协议的定时行为（即，我们保证特定关键级别的数据包截止时间得到满足）。虽然 AirTight 是一个新协议，但它是建立在 IEEE 802.15.4 等现有标准之上的。原型实现和协议精确模拟器也建立在现有技术的基础上，展示了协议的有效性和功能性。
This paper describes the motivation, design, analysis and implementation of a new protocol for critical wireless communication called AirTight. Wireless communication has become a crucial part of the infrastructure of many cyber-physical applications. Many of these applications are real-time and also mixed-criticality, in that they have components/subsystems with different consequences of failure. Wireless communication is inevitably subject to levels of external interference. In this paper we represent this interference using a criticality-aware fault model; for each level of interference in the fault model we guarantee the timing behaviour of the protocol (i.e. we guarantee that packet deadlines are satisfied for certainly levels of criticality). Although a new protocol, AirTight is built upon existing standards such as IEEE 802.15.4. A prototype implementation and protocol-accurate simulator, which are also built upon existing technologies, demonstrate the effectiveness and functionality of the protocol.
