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.

“…In all these algorithms the Proportional Fairness (PF) scheduler is used in-order to achieve channel awareness, which makes a trade-off between users' fairness and spectrum efficiency [2]. It schedule users in a fair way by taking into account both the experienced channel state and the past data rate when assigning radio resources.…”

“…There are many scheduling algorithms that exist in the literature that are used in the LTE scheduling process. These algorithms can be classified in five main groups: channel-unaware, channel-aware/QoS-unaware, channel-aware/QoS, semipersistent for VoIP support, and energy-aware [2]. When the number of users and their applications increases, such as video-streaming and video-conferencing, this requires higher data rates and decreased latency, which declines the service that the LTE provides to its users.…”

Long Term Evaluation (LTE) network, which primarily focuses on providing the high-speed communication for mobiles and other terminals/devices. In LTE the main mechanism is to process the traffic, which is done by the Packet Scheduler. Packet Scheduler is mainly responsible to send the packets to user nodes depending on the algorithm that is implemented at the Base Station. Packet scheduler is also responsible for queue management, scheduling of the packets, sending the packets to user nodes by allocating resources to them. Therefore, the key idea of paper is to implement a Scheduling Algorithm which meets the QoS requirements of LTE network. The performance analysis is done by comparing the NewQueue scheduling algorithm with the DropTail algorithm. Metrics that are used for comparing the performance are Throughput, Delay and Jitter.
