Cloud-Based Spectrum Sharing in Virtual Wireless Networks

On the evolution of infrastructure sharing in mobile networks: A survey

“…The VNO faces the problem of scheduling its users, each characterized by a maximum delay over a finite time period, through resources rented by the InP with the objective of minimizing the payments made to the InP for the rented resources. There are also articles which , it can be broadly classified into two groups based on whether the resource management is driven by pricing ([7,8,17,31,42,58,59,76,136,146,154,155]) or not ([50,62,63,68,73,79,97,123,130,132,133,138,151]). For instance, Ho et al in[58] consider the case when there is a single InP serving multiple MVNOs, each characterized by a fixed number of users and a Service Level Agreement (SLA) given in terms of a minimum resource requirement and a maximum aggregate rate (over all its users).…”

“…It should also be noted that the terms slicing and slice are also misused in some articles in non-5G contexts, in the sense that, such articles do not consider problem instances that account for 5G service requirements.There is a large body of literature on resource managements concerning InPs and SPs in the context of WNV. The vast majority of articles in this literature considers a single InP and multiple SPs (see e.g.,[7,8,17,31,42,50,58,59,62,63,68,73,76,79,97,123,130,132,133,136,138,146,151,154,155]). consider both multiple InPs and multiple SPs (and few other variations with multiple InPs) which however are more pertinent to Section 3.5 hence discussed therein.As for the literature on a single InP and multiple SPsInstead,Kamel et al in [73] address a scheduling problem over one time frame which is modeled through mathematical programming.…”
