“…Figure 9 represents the performance results of signaling cost in proposed mechanism on a time interval (seconds). In the previous framework [10], signaling cost is a critical issue which gives lower performance while our TM2M5G mechanism gives higher improvement in it. Our proposed method TM2M5G is flexible and scalable system that dynamically enable/disable related virtual network functions and employs new mechanism to improve the system capacity.…”

“…The analysis of the working mechanisms of SoftNet, including its dynamically defined architecture, decentralized mobility management, distributed data forwarding, and multi-RATs (Radio Access Technology) coordination, show that SoftNet has improved system capacity and performance. Simulations are conducted to demonstrate that signaling cost in SoftNet, as an important performance metric, can be decreased significantly compared with LTE networks [10].…”

“…Inter-access server handover takes place that results in more signaling cost at single hop itself. Table 2 compares the existing system called SoftNet [10] and our TM2M5G mechanism. The problems inSoftNetare compared with our mechanism.The parameters considered for simulation are signaling cost, bandwidth, delay, handover and throughput.…”

“…This may lead, for example, to control ow attacks [38] and bu er over ow attacks [39]. This issue is particularly important in the context of next-generation wireless networks, where the trend is to implement the control plane in software and to virtualize network functions [40,41] Flaws of NFV platforms: The virtualised environment itself could introduce many potential security problems [42]. In particular, aws of the virtualisation platform in place, may constitute the guest operating system (OS) vulnerable to side-channel attacks.…”

Abstract. Research on next-generation 5G wireless networks is currently attracting a lot of attention in both academia and industry. While 5G development and standardization activities are still at their early stage, it is widely acknowledged that 5G systems are going to extensively rely on dense small cell deployments, which would exploit infrastructure and network functions virtualization (NFV), and push the network intelligence towards network edges by embracing the concept of mobile edge computing (MEC). As security will be a fundamental enabling factor of small cell as a service (SCaaS) in 5G networks, we present the most prominent threats and vulnerabilities against a broad range of targets. As far as the related work is concerned, to the best of our knowledge, this paper is the rst to investigate security challenges at the intersection of SCaaS, NFV, and MEC. It is also the rst paper that proposes a set of criteria to facilitate a clear and e ective taxonomy of security challenges of main elements of 5G networks. Our analysis can serve as a staring point towards the development of appropriate 5G security solutions. These will have crucial e ect on legal and regulatory frameworks as well as on decisions of businesses, governments, and end-users.

“…Designers of future 5G architectures realized that the separation of user and control planes via SDN will improve the network flexibility, reconfigurability, and programmability, as well as will allow multi-tenancy and efficient multi-service support [8]- [10]. Although it was anticipated, since it has been a big challenge to apply SDN concepts in wireless and cellular environments, some recent research efforts show very promising results toward this direction [11]- [15].…”

Abstract-The concept of software-defined networking (SDN) is able to offer important advantages over the traditional communication paradigms. This is achieved by decoupling the decisionmaking process from the underlying network infrastructure that forwards the traffic. Recently, there have been efforts in applying the SDN approach to wireless and cellular networks. In fact, SDN is considered as one of the key enablers for future 5G communication networks. Information-centric networking (ICN) is another emerging communication paradigm that has been proposed to improve the content delivery efficiency compared to the traditional host-centric communication protocols. ICN decouples the data from their location, application, and means of transportation. This feature makes ICN particularly suitable for efficient dissemination of large volumes of data, especially in highly dynamic and heterogeneous mobile environments. In this work, we consider an SDN-enabled cellular network and propose an ICN protocol to ensure fast and efficient content dissemination to mobile users. The proposed protocol has been evaluated by means of computer simulations for the use case of a live video streaming service. Our experimental results show significant improvements in terms of response times over the current long-term evolution (LTE) networks.
