最初作为云计算的扩展，雾计算一直在激发将计算任务转移到网络边缘的新想法。在雾中，由于移动的用户的地理分布，我们经常重复放置服务的过程。我们可能不期望在用户和服务提供商之间存在固定的需求和供应关系，因为用户总是喜欢具有较少时延和传输消耗的附近服务。也就是说，即插即用的服务模式是我们在雾中所需要的。本文提出了一种动态的雾服务放置策略，以保证雾服务的正常提供和服务质量（QoS）的优化。仿真结果表明，我们的策略可以实现更好的性能指标，包括能源消耗和端到端的延迟。此外，我们还设计了一个基于Raspberry Pi和OpenFog的真实的即插即用雾（Plug-and-Play Fog，PnPF），为无线多媒体网络提供雾服务。
Initially as an extension of cloud computing, fog computing has been inspiring new ideas about moving computing tasks to the edge of networks. In fog, we often repeat the procedure of placing services because of the geographical distribution of mobile users. We may not expect a fixed demand and supply relationship between users and service providers since users always prefer nearby service with less time delay and transmission consumption. That is, a plug-and-play service mode is what we need in fog. In this paper, we put forward a dynamic placement strategy for fog service to guarantee the normal service provision and optimize the Quality of Service (QoS). The simulation results show that our strategy can achieve better performance under metrics including energy consumption and end-to-end latency. Moreover, we design a real Plug-and-Play Fog (PnPF) based on Raspberry Pi and OpenWrt to provide fog services for wireless multimedia networks.
