Social Network Aware Dynamic Edge Server Placement for Next-Generation Cellular Networks

A large amount of operational bandwidth is consumed due to the redundant data transmissions in a 4th Generation Long-Term Evolution (4G LTE) network and, thus, the operational latency of the network increases when message passing in a social network group is considered. In this paper, we propose a novel edge server placement strategy, Social network Aware Dynamic Edge Server placement (SADES), which uses the information from the overlay social network groups to efficiently identify a few influential base stations to place the edge servers, in an existing 4G LTE network. SADES can be utilized to design efficient ultra-reliable and low latency communication-enabled 5th Generation (5G) network.
