内容提要：
Fog computing is an emerging networking frontier which is proposed in 2000 and promoted by Cisco in 2012. In this talk, we will give an brief introduction to the fog computing paradigm, and demonstrate its application in vehicular content dissemination applications. In specific, we will present the design of a fog computing communication infrastructure which enables the localized vehicular content dissemination in city. The developed fog computing infrastructure is composed of distributed fog computer servers, where each fog server is a lightweight cloud-like virtualized system with limited buffer storage and is able to transmit wirelessly the cached contents to fast-moving vehicles. To enable the distributed fog servers working toward the global optimal performance (e.g., minimal average file download delays), a fully distributed algorithm to determine optimally the content replication strategy is presented. Using extensive simulations, we validate the effectiveness of the fog computing infrastructure and show that the proposed distributed protocol can approach to the optimal content dissemination performance and can significantly outperform the traditional heuristics.
