Edge Caching for Mobile Networks

Caching enables the storage of Internet-based content, including web objects, videos and software updates. When web objects are downloaded from the Internet or across wide-area-network (WAN) links, edge caching stores them at the edge of the network. Content can also be proactively cached at the edge based on its predicted popularity. When subsequent requests come for cached material, the content is quickly delivered from edge caching, without the need to download the data again over the WAN. The result is the ability to help save bandwidth, particularly at times of peak network load, increase content delivery, and provide users with a faster and better network experience.

Trusted Communications with Physical Layer Security for 5G and Beyond
Trung Q. Duong
The Institution of Engineering and Technology, 2017
Physical layer security is emerging as a promising means of ensuring secrecy in wireless communications. The key idea is to exploit the characteristics of wireless channels such as fading or noise to transmit a message from the source to the intended receiver while keeping this message confidential from eavesdroppers.
