Mobile Content Delivery
Requirement of Mobile Communication
The rapid increase of mobile traffic has placed a huge burden on current mobile networks , where the volume of content, the population of users, and types of mobile devices all keep growing quickly. Due to limited resources including power, spec?trum, etc., the related analysis shows that performance expectations cannot always be satisfied by various mobile network applications [18-21]. Besides, recent mobile networks are expected to support new emerging applications, such as tactile Internet, augmented reality, wearable devices, and smart mobile social communication, etc. The existing networks are not reliable enough to meet the performance requirements of these new applications. Accordingly, the efficient design of 5G mobile networks is needed.
According to the standards of 5G mobile networks, there are some detailed requirements related to capacity, data rate, latency, connectivity, operating cost, and QoE provisioning, respectively . For example, the aggregate data rate needs to be increased by 1000 times above the rate in 4G; the edge rate should be improved from 100 Mbps to 1 Gbps; the round time latency is expected to be 1 ms while it is 15ms in 4G .
Nowadays, there are massive efforts to design 5G mobile networks for the year 2020 and beyond. Among these efforts, as one of the most popular and practical network paradigms to provide content services, the design of MSNs is an important issue in 5G.
