“…In References [22,23], the authors present optimal and suboptimal strategies for placement of edge resources in 5G networks. In Reference [22], a framework to optimize the placement of primary and backup 5G user plane functions (UPFs) at the edge is provided.…”

“…However, the proposed model considers only backhaul links and do not account for the finite optical link capacity, which may affect the solution, especially when dealing with very high bitrate requirements of Fronthaul links. The model in Reference [23], instead, focuses on the number of edge nodes to be equipped with computational capacity, which is shown to increase with the number of base stations deployed in the area.…”

“…To model more closely real network scenarios, we assume that only a discrete set of capacity values can be chosen by the network operator and made available. Therefore, we adopt a piecewise-constant function S i for the processing capacity of an edge node, in line with [6]. This is defined as:…”

“…The authors in [12] propose a mixed integer linear programming (MILP) model to study cloudlet placement, assignment of access points (APs) to cloudlets and traffic routing problems, by minimizing installation costs of network facilities. The work in [6] proposes a MILP model for the problem of fog nodes placement under capacity and latency constraints.…”

“…To decrease the EN network costs, we aim to optimize the site selection and reduce the number of ENs deployed and the capacity assigned to each EN. The underlying problem formulation models the service demand, distributed over a given area, as traffic generators (TGs) [23]. In more detail, the aggregated cell structure composed by the TGs in the form of 4G/5G mobile base stations, wireless access points, etc., is considered to be known.…”
