摘要: Cities around the world are evaluating potential of Internet Things (IoT) to automate and optimize public services. that implement this approach commonly referred as smart cities. A city IoT architecture needs be layered scalable in order fulfill not only today's but also future Network Function Virtualization (NFV) provides scale flexibility necessary for services by enabling automated control, management orchestration network resources. In paper we consider a scalable, layered, NFV based discuss optimal location applications regarding cloud computing mobile edge (MEC). Introducing novel concept dynamic application allocation show how fully benefit from MEC present relevant decision criteria.
