“…The software-defined networking (SDN) and network function virtualization (NFV) promote the new trend of virtualizing mobile network functions into softwarebased cloud servers with the aim to resource optimal utilization [41,125,126]. The use of virtualization in mobile caching network can stimulate MNOs to adjust their functions in an online manner dynamically.…”

The demand for content oriented service and compute-intensive service stimulates the shift of current cellular networks to deal with the explosive growth in mobile traffic. Information centric mobile caching network architectures have emerged in Information-Centric Networking as well as mobile cellular and ad-hoc networks deployed with caches. Caching optimization based on information centric mobile caching has become the key issue, and several significant research challenges remain to be addressed before its widespread adoption. In this paper, a brief survey on Information centric mobile caching network architecture and caching optimization is presented, including cache placement in different mobile wireless network architectures, the taxonomy of cache insertion and eviction policies, the modeling behavior of caching networks as well as caching optimization based on network centric and user centric metrics, and typical applications based on mobile caching. Finally, the research directions and open challenges are investigated.

“…Although these methods advance the field of spectrum resource allocation, because the input and the output resources are not of the same type, these techniques cannot be considered recursive, and subsequently do not fall under our strict definition of virtualization. Similarly, the work [75] proposes a spectrum resource sharing technique that relies on estimating the users' traffic requirements, and thus the output resources are at a higher level of representation than the input resources.…”

Virtualization is a topic of great interest in the area of mobile and wireless communication systems. However the term virtualization is used in an inexact manner which makes it difficult to compare and contrast work that has been carried out to date. The purpose of this paper is twofold. In the first place, the paper develops a formal theory for defining virtualization. In the second instance, this theory is used as a way of surveying a body of work in the field of wireless link virtualization, a subspace of wireless network virtualization. The formal theory provides a means for distinguishing work that should be classed as resource allocation as distinct from virtualization. It also facilitates a further classification of the representation level at which the virtualization occurs, which makes comparison of work more meaningful. The paper provides a comprehensive survey and highlights gaps in the research that make for fruitful future work. arXiv:1705.03768v2 [cs.NI] 4 Jul 2018 Physical DomainR ASCII p(bin) 01101011 binary k character Abstract Domain RASCIĨ RBIN RBIN Representation Level 2: Representation Level 1:

“…Wang et al suggested a packet switching scheme to improve performance of wireless network virtualization by locating frames into user space and by placing control and data frame in kernel space . In the work of Feng et al, a hierarchical control‐based cell clustering model is suggested to integrate heterogenous wireless network and to coordinate among network resources toward optimizing resource utilization.…”

Virtualization technology has revolutionized the mobile network and widely used in fifth‐generation innovation. It is a way of computing that allows dynamic leasing of server capabilities in the form of services like Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). The proliferation of these services among the users led to the establishment of large‐scale cloud data centers that consume an enormous amount of electrical energy and results into high metered bill cost and carbon footprint. In this paper, we propose three heuristic models, namely, median migration time, smallest void detection, and maximum fill technique, that can reduce energy consumption with minimal variation in service‐level agreements negotiated. Specifically, we derive the cost of running cloud data center, cost optimization problem, and resource utilization optimization problem. Power consumption model is developed for cloud computing environment focusing on linear relationship between power consumption and resource utilization. A virtual machine (VM) migration technique is considered, focusing on synchronization‐oriented shorter stop‐and‐copy phase. The complete operational steps as algorithms are developed for energy‐aware heuristic models including median migration time, smallest void detection, and maximum fill technique. To evaluate the proposed heuristic models, we conduct experimentations using PlanetLab server data often in ten days and synthetic workload data collected randomly from the similar number of VMs employed in PlanetLab servers. Through evaluation process, we deduce that the proposed approaches can significantly reduce the energy consumption, total VM migration, and host shutdown while maintaining high system performance.
