Of late years, a growing number of mobile devices are demanding computation-intensive tasks with low delay requirements. Edge computing, where mobile devices offload their tasks to servers installed on the edge nodes of a network closer to the mobile devices, enables faster completion of the computation-intensive tasks. To offer low delay with a limited number of servers, efficient computing server deployment and user offloading associations resulting from the deployment are consequential. However, the existing research on server deployment and user offloading associations is restricted to heuristic algorithms failing to address joint optimization due to its prohibitive complexity. In contrast, this paper studies the joint design of computing server deployment and user offloading associations in wireless edge networks with wireless backhaul, enabling broadband transmission at a lower cost than the existing wired …
