Video Application on Ultra-Dense Network

The exponential growth and availability of data is the main driving force to the continuing evolution in the communication industry. The mobile video traffic is the main component of the immense amount of traffic generated by smart devices and requires a paradigm shift in all aspects of mobile network. Ultra-dense network (UDN) is one of the leading ideas where the access nodes and the communication links per unit area are densified. In this paper, we provide an introduction of UDN and video services. The relative techniques are summarized as well as the recent finding. Finally, we discuss the problems to the researchers in the field of video application in UDN.
