Fog computing not only executes applications in the vicinity of the IoT devices/users but also keeps transient data which removes the need for data transfer to the cloud on regular basis. For applications’ placement, an orchestrator considers the requirement of the application and the current fog status to place the application on suitable fog nodes. The orchestrator itself may be placed on fog or cloud nodes. In a centralized approach, a fixed entity that works as an orchestrator is prone to single point failure, less mobility support, etc. Therefore, the literature advises for a decentralized approach in which a nearby fog node is selected to act as an orchestrator. Poor selection of Fog Orchestrator Nodes (FONs) may result in the performance degradation of the system. None of the earlier work proposed the selection of FON for the placement of the applications on the fog nodes. Towards this, a brief but latest survey of the works, to understand the FON selection problem, is done along with the importance of decentralized approach in the FON selection problem. Further, few performance metrics have been identified which helps in the FON selection. A lightweight FON Selection model (FONS) is proposed so that even the least powerful IoT devices can select a FON. The proposed work is validated by incorporating the FON selection algorithm in one state of art to observe a remarkable improvement in application placement.

FONS:雾协调器节点选择模型,可改善雾计算中的应用程序放置

雾计算不仅可以在IoT设备/用户附近执行应用程序,而且还可以保留瞬态数据,从而无需定期将数据传输到云中。对于应用程序的放置,协调器会考虑应用程序的要求以及当前的雾状态,以将应用程序放置在合适的雾节点上。协调器本身可以放置在雾或云节点上。在集中式方法中,充当协调器的固定实体容易出现单点故障,移动性支持较少等问题。因此,文献建议采用分散式方法,其中选择附近的雾节点作为协调器。雾协调器节点(FON)的选择不当可能会导致系统性能下降。较早的工作都没有提议选择FON来将应用程序放置在雾节点上。为此,完成了对作品的简短但最新的调查,以了解FON选择问题,以及在FON选择问题中分散方法的重要性。此外,几乎没有性能指标可用于FON选择。提出了轻量级的FON选择模型(FONS),以便即使功能最弱的IoT设备也可以选择FON。通过将FON选择算法并入一种最新技术中来验证所提出的工作,以观察到应用程序放置方面的显着改进。以及在FON选择问题中分散方法的重要性。此外,几乎没有性能指标可用于FON选择。提出了轻量级的FON选择模型(FONS),以便即使功能最弱的IoT设备也可以选择FON。通过将FON选择算法并入一种最新技术中来验证所提出的工作,以观察到应用程序放置方面的显着改进。以及在FON选择问题中分散方法的重要性。此外,几乎没有性能指标可用于FON选择。提出了轻量级的FON选择模型(FONS),以便即使功能最弱的IoT设备也可以选择FON。通过将FON选择算法并入一种最新技术中来验证所提出的工作,以观察到应用程序放置方面的显着改进。
