物联网（IoT）网络预计将可靠运行多年，同时满足日益增长的应用需求。然而，由于IoT设备的可靠性降级，可能并不总是保持可靠的操作。从低功耗传感器到多核平台，物联网设备会老化和退化，导致需要维护的故障。可靠性意识的设计和管理被证明可以延迟故障并提高单个设备的寿命。尽管物联网网络也可以从中受益，但提供可靠性建模的网络模拟器的不可用使得无法评估可靠性感知策略。为了弥补这一差距并在早期设计阶段进行可靠性分析，我们引入了一个名为RelIoT的物联网集成可靠性框架，该框架在ns-3模拟器中实现。该框架还包括对可靠性建模所需的功耗、性能和温度的建模。我们验证了使用我们的框架进行的模拟，并证明RelIoT准确地捕捉了真实的联网物联网设备的功率，温度和可靠性动态。
The Internet of Things (IoT) networks are expected to operate reliably for many years while meeting the needs of a growing range of applications. However, a dependable operation may not always be maintained due to the reliability degradation of IoT devices. From low-power sensors to multi-core platforms, IoT devices age and degrade, leading to failures that necessitate maintenance. Reliability-aware design and management were shown to delay failures and improve the lifetime of individual devices. Even though the IoT networks can also radically benefit from this, the unavailability of network simulators that provide reliability modeling makes it impossible to assess reliability-aware strategies. To bridge this gap and enable reliability analysis at an early design phase, we introduce an integrated reliability framework called RelIoT for IoT networks, implemented in the ns-3 simulator. The framework also includes modeling of power, performance, and temperature, which are required to model reliability. We validate the simulations done using our framework and demonstrate that RelIoT accurately captures the power, temperature, and reliability dynamics of real networked IoT devices.
