On Virtualization and Security-Awareness Performance Analysis in 5G Cellular Networks

Abstract

Recently, Fifth Generation (5G) cellular networks have gained promise as a paradigm that could provide rich computational resources for users. Virtualization is a key technology for wireless communications, especially in standard Long Term Evolution (LTE) systems, which enable cloud based multi-tenancy business models through providing a shared scalable resource platform for all users. Despite the potential significance of virtualization for cellular networks, several challenges remain to be addressed. For cellular networks, providing multiple levels of security is essential to support different levels in information sensitivity. However, placing different customers' services requirements on a virtualized evolved Node B's (eNB's) scheduler may lead to noticeable security vulnerabilities. In this work, we present an overview of cellular network security issues in a fully virtualized environment along with their preventative measures. Virtualization is implemented by allowing service providers to share their resources while performing different scheduling policies and sharing one eNB. To evaluate the considered framework, the average delays for different traffic types were measured. The results of the simulation showed that virtualization could noticeably reduce average user equipment delay compared with the non-sharing scheme.

“…D2D networks [14][15][16] are key networks that will serve the communication, coverage, and data rate demands for any future applications. Currently, D2D has received much attention from Some examples are Relay-By-Smartphone [5] and Data Spotting [6], and FlashlineQ [5] can provide connectivity up to 1 KM [6].…”

A Survey on the Security and the Evolution of Osmotic and Catalytic Computing for 5G Networks

“…Considering the reachability and number of devices active in 5G networks, the scale and the impact of these attacks becomes severe and allows zero time to respond. Efficient mutual authentication, strong key agreements should be followed while deploying applications in 5G networks, however, these should come without affecting the performance of the network [25]- [27]. Although 5G networks aim at increasing the speed as well as the quality of the transmissions, this reduces the time window for applying security mechanisms to prevent any active attacks on the networks.…”
