In order to better accommodate the dramatically increasing demand for data caching and computing services, storage and computation capabilities should be endowed to some of the intermediate nodes within the network, therefore increasing the data throughput and reducing the network operation cost. In this paper, we design a novel information-centric heterogeneous networks framework aiming at enabling...
Network Function Virtualization (NFV) is a promising solution for telecom operators and service providers to improve business agility, by enabling a fast deployment of new services, and by making it possible for them to cope with the increasing traffic volume and service demand. NFV enables virtualization of network functions that can be deployed as virtual machines on general purpose server hardware...
With the development of computers, the Internet and mobile technologies, different needs have emerged for people and different solutions have been discovered to meet these needs. One of the critical areas which are considered as the main factor in creating the tomorrow of human beings where a careful study should be done is the education and teaching. Many technologies are being used and various methods...
The problem of managing the scarce radio spectrum resource is addressed in this paper; based upon the Worldwide Interoperability for Microwave Access (WiMAX) network. Emerging and innovative techniques such as spectrum virtualization and network federation are adopted to enable the sharing of spectrum amongst mobile operators. A novel entity known as the Virtual Spectrum Hypervisor (VS-Hypervisor)...
Mobile Broadband (MBB) access networks are becoming more and more used worldwide, and the devices adopted to access them are increasing in number and complexity (smart-phones, mobile hotspots, vehicular infotainment systems). The highly dynamic nature of such scenarios calls for continuous monitoring and measurement of the network. To this aim, the Available Bandwidth is a performance metric of the...
Wireless networks have gone through several years of evolution until now and will continue to do so in order to cater for the varying needs of users. These demands are expected to grow in the future, both in size and variability. Hence, the 5G technology considers these variabilities in service demands and potential data explosion which could accompany users' demands at the core of its architecture...
This paper describes the experimentation on the Future Internet Research & Experimentation (FIRE) Long Term Evolution (LTE) testbeds for open experimentation (FLEX) facilities by combining the existing Evolved Node B (eNB) with an execution infrastructure. In this direction, LTE Edge Network Enhancement with Core Functionalities (LENA) project will enhance the LTE FLEX testbed with a Network Function...
Software-Defined Networking (SDN) paradigm provides many features including hardware abstraction, programmable networking and centralized policy control to networks. In the next generation mobile networks, one of the main benefits that can be used along with these features is core/backhaul SDN-based network virtualization. In this article, we propose a novel shared SDN-based Evolved Packet System...
There are some corporate policies in most of companies around the world, focus on mobile devices to be used as BYOD (Bring Your Own Device), but in Ecuador, these policies are not being established yet. In spite of that, this technology has been used frequently, even do some employers don't allow to use employees' mobile devices because of the inherent security risks, without being aware that BYOD...
Mobile offloading overcomes the resource limitations of offloader devices by splitting resource-intensive tasks and allocating subtasks to nearby offloadee devices. In processing its subtask, each offloadee effectively executes foreign and untrusted code which might both harm the device and exhaust its resources. Given the personal nature and constrained resources of offloadee devices, such as smartphones,...
The sovereignty of cloud-deployed media applications and services is improbable to be disrupted in the foreseeable future. This paper aims to provide an overview of the most essential technologies utilized by this constantly evolving cloud ecosystem, identify the design principles of a media-aware cloud and present an architectural position based on the research conclusions. An end-to-end quality-aware...
The COMPA (Control, Orchestration, Management, Policy, and Analytics) adaptive control loop realizes an automation pattern that can operate recursively at many layers in a carrier network. An overall COMPA autonomic control loop can orchestrate functions, themselves implemented as COMPA autonomic loops. Thus the COMPA automation patter can recurse right down to resource level in a network. One of...
Radio Access Network (RAN) sharing and Cloud-RAN (C-RAN) are two major candidates for next generation mobile networks. RAN sharing ensures efficient usage of network equipments among multiple mobile network operators (MNOs) and C-RAN benefits installation, evolution, management and performance improvements. Similarly, Software-Defined Networking (SDN) concept provides many features including hardware...
Cloud radio access network (C-RAN) centralizes several baseband units to form a pool, which is the primary form of the wireless network virtualization. Some aspects of C-RAN are always developing, such as the processing capacity and multiple radio access technology (multi-RAT) convergence. In this paper, the Not Only Stack (NO Stack) framework, as a virtualization approach, is suggested to be employed...
With the explosive growth of smartphones and cloud computing, mobile cloud, which leverages cloud resource to boost the performance of mobile applications, becomes attrac- tive. Many efforts have been made to improve the performance and reduce energy consumption of mobile devices by offloading computational codes to the cloud. However, the offloading cost caused by the cloud platform has been ignored...
In this paper, we propose a novel cellular network architecture including network virtualization controller for mobile core and backhaul sharing. Software-Defined Networking (SDN) based network virtualization is applied into Evolved Packet System (EPS) architecture of Long Term Evolution (LTE) networks. After virtualization of all evolved Node-Bs (eNodeBs) associated with different Mobile Operators...
In this paper, we proposed a novel locally semi-stand alone Smart Virtual evolved Base Station (SVeNB), for 5G mobile communication. Where some functions of system Evolved Packet System (EPS) elements can be done with SVeNB. According to the type of function or service and the device, which is used to fulfil that function or service. These elements can be virtualized and programmed in one Virtual...
The development of Fog Computing technology is crucial to address the challenges to come with the mass adoption of Internet Of Things technology, where the generation of data tends to grow at an unprecedented pace. The technology brings computing power to the surrounds of devices, to offer local processing, filtering, storage and analysis of data and control over actuators. Orchestration is a requirement...
Mobile cloud computing is a wide-ranging blend of cloud computing and mobile development. It is a technique in which mobile applications are assembled, functioned and presented using cloud computing technology. The hastening in the advancement of cloud computing as well as mobile computing has led to the invention of an amalgamated output: Mobile Cloud Computing. These days, this is becoming one of...
Mainly due to exponential growth in smart devices based mobile computing, the access networks are gaining tremendous momentum.
