5G networks aim to support a number of vertical industries that are characterized by diverse performance requirements. Network slicing is considered be the key enabler enhance cellular with desired flexibility achieve this target. During past years, network concept has been thoroughly studied, and main operational principles have established. However, added complexity introduced creates some issues still under investigation. This article provides comprehensive overview solutions proposed...
While there is clarity on the wide range of applications that are to be supported by 5G cellular communications, and standardization has now started in 3GPP, no conclusion yet detailed design overall RAN. This article provides a comprehensive overview RAN guidelines, key considerations, functional innovations as identified developed players field.1 It depicts air interface landscape envisioned for 5G, elaborates how this will likely harmonized integrated into an RAN, form concrete control...
Network slicing addresses the deployment of multiple logical networks as independent business operations on a common physical infrastructure. The concept has initially been proposed for 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> Generation (5G) core network (CN) however, it not investigated yet what would represent to design 5G radio access (RAN). paper explains how may impact several aspects RAN such protocol architecture,...
Abstract The heterogeneity in use cases and the need to support diverse requirements from vertical markets are main drivers for new design principles of 5G communication systems. In this paper, we review notion plastic architecture propose an end network slicing concept serve capabilities features a flexible efficient manner. Besides definition, address particular key issue how devices may be enabled discover, select access most appropriate E2E slices. To solve issue, developed novel Device...
The integration of existing cellular systems with new wireless access technologies, such as LANs, has attracted considerable attention during the past few years. challenges to be addressed include authentication, security, QoS support, and mobility management. Efficient management, especially handover is considered one major factors toward a seamless provision multimedia applications across networks different technologies. A large number solutions have been proposed in an attempt tackle all...
The Future Internet is expected to greatly influence how the food and agriculture sector currently operating. In this paper, we present specific characteristics of agri-food focusing on information management in area will take place under a highly heterogeneous group actors services, based EU SmartAgriFood project. We also discuss new dynamic marketplace be realized adoption number specialized software modules, called "Generic Enablers" that are developed context FI-WARE Thus, paper presents...
The Agriculture business domain, as a vital part of the overall supply chain, is expected to highly evolve in upcoming years via developments, which are taking place on side Future Internet. This paper presents novel Business-to-Business collaboration platform from agri-food sector perspective, aims facilitate numerous stakeholders belonging associated domains, an effective and flexible manner. contemporary B2B schemes already requirements for swift deployment cloud applications, capable...
The long-term evolution multimedia broadcast multicast service (MBMS) infrastructure has been shown to efficiently fulfill the requirements of classical vehicle-to-vehicle services, such as cooperative awareness message and decentralized environmental notification delivery, which involve transmission same a set destination receivers in close proximity. When targeting autonomous driving applications, related 5G V2X collision avoidance (CCA), impose challenging latency reliability that cannot...
Vehicular communications is expected to be one of the key applications for cellular networks during following decades. Key international organizations have already described in detail a number related use cases, along with their requirements. This article provides comprehensive analysis these cases and harmonized view requirements latest most advanced autonomous driving applications. It also investigates extent support that 4G 5G can offer terms delay spectrum needs. The paper identifies...
The current technological advances in mobile telecommunication networks and the Internet are about to alter existing business models. These different worlds converge create an open market, where a large number of independent application/service providers will offer their services users through limited network providers. At same time, evolution technologies specification new concepts requires advanced holistic solutions several technical areas. One such area is related design management...
As the automotive industry moves toward fully autonomous driving, goal is to enable vehicles operate safely without human control in all environments. Implementing Vehicle-to-Everything (V2X) communications highway environments poses considerable challenges. Several critical services have strict network performance requirements as they deal with safety features. Existing fifth-generation (5G) base station schedulers do not discriminate among and non-critical automated driving functions....
The vast increase in the number of mobile devices and their traffic demands indicates need for additional spectrum cellular communications. Since it is not trivial to allocate exclusively new bands communications, imperative improve usage through sharing mechanisms. This implies that network operators will have cooperate interact cover augmented requirements. In this article we present a novel architectural framework enables other license holders exchange information about availability. We...
Mobile network operators are interested in providing Vehicle-to-Vehicle (V2V) communication services using their cellular infrastructure. Regional split of is one possible approach to support multi-operator infrastructure-based V2V communication. In this approach, a geographical area divided into non-overlapping regions, each served by unique operator. Its main drawback the interruption motivated inter-operator handover border areas, which prevents fulfillment maximum end-to-end (E2E)...
The design of an efficient radio access selection mechanism for 5G cellular networks is paramount importance. Several proposals exist in the literature, but up to now deployed systems are still using simple mechanisms mainly related evaluation RSS make a handover decision. However, this inadequate solution networks.
