尽管移动的设备正在获得越来越多的能力（即CPU能力、存储器、连接性等），但它们仍然不足以执行复杂的丰富媒体和数据分析应用程序。卸载到云并不总是一个解决方案，因为广域网延迟很高，特别是对于具有实时约束的应用程序，如增强现实。因此，云必须以微云的形式更接近移动的用户。我们提出了一个更细粒度的cloudlet概念，在组件级别上管理应用程序，而不是将一个完整的虚拟机从云移动到cloudlet。Cloudlet不一定是靠近无线接入点的固定基础设施，而是可以通过LAN网络中的任何设备以动态方式形成。我们提出了一个cloudlet架构连同一个原型实现，展示了移动的实时增强现实应用的优势和能力。
Although mobile devices are gaining more and more capabilities (i.e. CPU power, memory, connectivity, ...), they still fall short to execute complex rich media and data analysis applications. Offloading to the cloud is not always a solution, because of the high WAN latencies, especially for applications with real-time constraints such as augmented reality. Therefore the cloud has to be moved closer to the mobile user in the form of cloudlets. Instead of moving a complete virtual machine from the cloud to the cloudlet, we propose a more fine grained cloudlet concept that manages applications on a component level. Cloudlets do not have to be fixed infrastructure close to the wireless access point, but can be formed in a dynamic way with any device in the LAN network with available resources. We present a cloudlet architecture together with a prototype implementation, showing the advantages and capabilities for a mobile real-time augmented reality application.
