An expansion of services and unprecedented traffic growth is anticipated in future networks, aligned with the adoption long-awaited Fifth Generation (5G) mobile communications. To support this demand, without exposing operators to pressure CAPEX OPEX, 5G uses new frequency bands, adopts promising trends, including: densification, softwarization, autonomous management. While first technology proposed handle requirements, softwarization management are expected play, synergy, ensure desired...
As 5th Generation research reaches the twilight, community must go beyond 5G and look towards 2030 connectivity landscape, namely 6G. In this context, work takes a step 6G vision by proposing next generation communication platform, which aims to extend rigid coverage area of fixed deployment networks considering virtual mobile small cells (MSC) that are created on demand. Relying emerging computing paradigms such as NFV (Network Function Virtualization) SDN (Software Defined Networking),...
C-RAN presents an advanced mobile networking architecture that promises to tackle various challenging aspects of 5G such as increasing energy efficiency and providing high capacity. Indeed, paves the way toward better by centralizing baseband processing at cloud computing based servers (BBU pool). In this paper, we propose RRH group mapping (RGBM) aims minimize power consumption BBU pool, while considering users' QoS capacity constraints. To achieve this, proposed scheme uses two key steps:...
Future networks are envisaged to support an increasingly wide range of diverse services, with distinct service requirements. Network slicing presents economically sustainable solution properly handle these stringent requirements, on top a common physical infrastructure. The network at different Radio Access (RAN) resource management tasks is particularly challenging, as it involves the dynamic split scarce radio resources among slices, aiming achieve optimal share traffic isolation slices....
-Performance of Vehicular Adhoc Networks (VANETs) in high node density situation has long been a major field studies. Particular attention paid to the frequent exchange Cooperative Awareness Messages (CAMs) on which many road safety applications rely. In present paper, se focus European Telecommunications Standard Institute (ETSI) Decentralized Congestion Control (DCC) mechanism, particularly evaluation its facility layers component when applied context dense networks. For this purpose, set...
This work aims to minimize the power consumption of cloud virtualization components by addressing important challenge designing allocation schemes that cater for both radio and computational resources in a virtualized cloud-based environment. Unlike previous efforts, we consider realistic behavior resource heads (RRHs) associated with one baseband unit (BBU), acting as DAS. We first formulate admission control (AC) RRH–BBU mapping problem, subject constraints on user throughput requirements,...
The emerging vehicular ad-hoc networks (VANETs) have paved the way to Cooperative Adaptive Cruise Control (CACC) applications. With such application, cars can travel in platoons with very small headways and thus achieve considerable capacity fuel consumption gains. In order ensure safety while exploiting gains, intra/inter-platoon communications rely on a fast reliable information exchange. Thus, it is important define relaying schemes which that platoon applications be run over unreliable...
Coordinated vehicles travelling in platoons can improve road capacity, reduce fuel consumption and offer a more comfortable experience for the driver. However, platooning to achieve such gains, headway distances between cars have be kept small even at high speeds. The feasibility of approach, hence relies entirely on availability fast reliable information exchange vehicles, which occurs over an unreliable wireless communication channel. In this paper, we analyse dissemination safety related...
In this paper, we propose a Multi-Operators resource allocation scheme, where the available bandwidth of Heterogenous Cloud RAN (H-CRAN) is shared among different Virtual Mobile Network Operators (VMNOs), according to static, as well adaptive sharing. We evaluate performance two schemes, in terms average spectrum utilization efficiency, user satisfaction metrics and throughput. Results show that sharing brings considerable gain performance, with respect these evaluation compared static...
