In recent times, mobile broadband networks are focused on bringing different capabilities to the edge of the mobile network. Mobile Edge Computing (MEC) addresses this issue by placing the compute and storage resources closer to the Radio Access Network (RAN), with an aim to reduce end-to-end latency, ensure better service delivery, and offer improved user experience. In this work, we propose SDEC...
Recently, mobile broadband networks are focused on bringing additional capabilities to the network edge. For instance, Mobile Edge Computing (MEC) brings storage and processing capabilities closer to the mobile user i.e., at the radio access network, in order to deploy services with minimum delay. In this paper, we propose a resource constrained cloud-enabled small cell that includes a MEC server...
Due to the ubiquitous presence of cellular networks and their exemplary success, they have been pushed forward to provide connectivity for Internet-of-things (IoT) applications with mass deployments of sensors and machines. Nevertheless, existing transmission protocols, e.g., orthogonal allocation or spectrum sharing, can be detrimental for both existing cellular users and IoT devices due to increased...
In the 5G era, radio IP capacity is expected to reach 20 Gbit/s per sector, and ultra-large content traffic will travel across the faster wireless/wireline access network and packet core network. Also massive and mission-critical IoT is the main differentiator of 5G services. These types of real-time and large-bandwidth consuming services require radio latency of less than 1ms, and end-to-end latency...
To alleviate the pressure brought by the explosion of mobile video traffic on present cellular networks, small cell base stations (SBS) with caching ability are introduced. In this paper, we consider the caching strategy using network coding for mobile users over heterogeneous wireless network containing SBSs. We formulate an integer programming problem to minimize the average number of packets downloaded...
Heterogeneous vehicular networks (HetVNets) are a promising approach to meet the various communication requirements of vehicular networks' services using a variety of available access networks. However, due to their inherited characteristics, HetVNets are rigid, difficult to manage and suffer from a lack of programmability, flexibility, and scalability. In this paper, we first highlight the limits...
The Internet was designed to support host-oriented services. However, users are typically interested in the content itself rather than the location of the content. As the usage of the Internet for content retrieval is increasing rapidly, some intelligent methods have to be employed in the base stations to provide faster and seamless content delivery. In this paper, we propose a CCN-based fast content...
The Xhaul architecture presented in this article has a goal of developing a 5G integrated backhaul and fronthaul transport network enabling flexible and software-defined reconfiguration of all networking elements in a multi-tenant and service-oriented unified management environment. The Xhaul transport network is required to have the capability of carrying multiple traffic, such as CPRI and Ethernet,...
Emerging services for Intelligent Transport Systems put the information content at the centre of the communication process, require a seamless support of mobile users, and target a real-time and asynchronous data dissemination. The Information-Centric Networking paradigm has all the potentials to fulfill these requirements, thanks to its ability to distribute contents through publish-subscribe communication...
The Crowdsensing-based systems using mobile technology create a new kind of collective intelligence in a sensing environment mediated by ICTs. On the other hand, ICTs and social networks contribute to the emergence of virtual communities. The interaction among participants can create dynamically groups from a previously known platform where all participants perform tasks and solve problems in a specific...
Next generation technologies are being tried to develop for 5G wireless cellular networks nowadays by many researchers. Some key technologies provide significant improvements for 5G systems in terms of huge capacity, higher data rate, signaling overhead on the network and energy-spectral efficiency. etc., But these technologies also bring along critical challenges for 5G systems. In this study, these...
Edge computing is a recent paradigm where network nodes are placed close to the end users, at the edge of the network. Efficient management of resources within this configuration is crucial due to scarcity and geographical spreading of edge resources. We begin by a brief description of the edge paradigm, the most generic edge architecture, and the terminology associated to it. Then, we propose and...
A smart campus refers to a campus where modern information and communication technologies bring more convenience to campus life, assist campus users to improve and more efficiently accomplish their daily activities, and enhance social interactions. Regarding the high demand of services such as mining campus users' semantic information, building augmented reality assisted mobile campus and smart class,...
The continuous evolution of mobile networks is demanding and promising. The increase in mobile population, the introduction of new applications and use cases which represents a major shift in the paradigm from voice to data especially with the adoption of the IP network from the internet in the mobile networks. This has imposed challenges in current architecture of mobile networks in terms of backhaul...
5G tends to be a multi-layered, multi-actor, and multi-access mobile network in order to fulfill the stringent availability, security, privacy and resilience requirements that are usually contradictory. In this paper, we propose a 5G vision based on softwarization. We provide a non-exhaustive list of current security, trust and resilience issues that are critical to be explored in 5G. We finally give...
In this paper, we present the Dynamic Small cell Management (DSM) scheme to improve vehicular communications, focusing on the dynamic allocation of small cells when the macrocells cannot cope with the traffic generated by the connected cars. We have considered real base station deployments in the city of Dublin, Ireland, combined with realistic models of vehicle mobility, and small cell deployments...
The rapid development of intelligent terminals and mobile Internet industry has brought many challenges and opportunities to the mobile network. Mobile Network Open Services can provide users and developers with the open resources consisted of network infrastructure, network data and diversified services, so as to build an open, flexible, collaborative Internet ecosystem. The ability to open the mobile...
Facilitated by the emerging technologies of cloud computing, vehicular cloud computing (VCC) is being expected to be a new paradigm to create a new situation for vehicular data services. However, with the increasing popularity of vehicular cloud services, accessing vehicular terminals and produced mobile data are experiencing tremendous growth, therefore, how to provide enough capacity for all access...
