Machine to Machine (M2M) or Machine Type Communication (MTC) is one of the emerging 5G technologies and represents a key component of Internet of Thing (IoT). In M2M networks a key challenge is to overcome the overload and congestion problems caused by random access requests from massive MTC devices. Hence to deal with Random Access channel (RACH) overload and to better control the Access the 3GPP...
Offloading to external extra resources total or part of the workload generated by applications running on mobile handsets has been proposed as a way to enhance mobile user quality of experience. However, allocating offloading requests to virtual machines (VMs) is one of the most challenging problems in the cloud computing domain area. In this paper, we consider a Cloud Radio Access Network (C-RAN)...
Cloud Radio Access Network (Cloud RAN) is novel mobile network architecture. It uses cloud computing capabilities to enhance the quality of service (QoS) in next generation 5G networks. The basic concept of Cloud RAN is to separate the digital baseband processing units (BBUs) of conventional cell sites, from the Remote Radio Heads (RRHs), and move them to the cloud for centralized signal processing...
Cloud Radio Access Network (C-RAN) is a novel mobile network architecture that brings baseband processing units (BBUs) of a set of base stations into a central server keeping only remote radio heads (RRHs) at the cell sites. Because of their limited resources, running sophisticated applications on mobile handsets could result in poor performances and shortened battery lifetime. One promising solution...
Cloud Radio Access Network (C-RAN) is a novel mobile network architecture which is deemed to be one of the most promising evolution trends towards future networks. The basic concept of cloud-RAN is to separate the digital baseband processing units (BBUs) of conventional cell sites, from the Radio Remote Heads (RRHs), and move them to the cloud (BBU pool) for centralized signal processing and management...
Machine - to - Machine communication (M2M) also known as Machine Type communication (MTC), in 3GPP LTE systems, is expected to play an important role to realize Internet of Things (IoT). In fact, it is considered as an emerging technology to provide ubiquitous connectivity among devices without human intervention. Due to its wide coverage and Heterogeneous Networks(HetNets), the next generation of...
The proliferation of mobile handsets has undoubtedly spurred on developers to build a large variety of applications that allow users to better exploit their powerful devices. However, running multiple sophisticated applications could result in poor performances and shortened battery lifetime. Mobile data offloading to edge cloud offers a promising solution to enhance both QoS and battery life of mobile...
Inter cell interference is one of the most serious problems in LTE-Advanced networks and beyond (5G). This issue is the direct result of two major features: the frequency reuse factor equal to one and the heterogeneous deployment of networks (HetNets). Many solutions have been proposed by the 3GPP project since its early Release 8 in order to mitigate interference. The most recent one is Coordinated...
Energy consumption of Information and Communication Technologies (ICT) in general and wireless mobile networks in particular is rapidly increasing with the exponential growth of data bit rates. For environmental and cost reduction purposes, the telecommunication industry is looking for Green (energy efficient) networks implementation. In this paper, we focus on the Handover procedure in LTE-A / 5G...
Self-Organizing Network, or SON, is a new technology that aims to minimize human efforts spent in management and operating processes. In technical term; this solution was proposed to reduce the operational expenditure for service providers in future wireless systems since it offers the possibility of automatic and remote managing of mobile networks especially in LTE-Advanced and beyond, coming within...
Among the major challenges in 3GPP LTE-A (3rd Generation Partnership Project Long Term Evaluation) and beyond networks are the convergence of services towards IP technology, the quality of service (QoS) and the maintenance of multimedia flows transmitted on wireless networking for mobile and heterogeneous users. In this environment, multimedia services must face various disadvantages generated by...
Fourth generation networks and beyond have recently emerged to satisfy the increasing demand for high data rates. Cost-effective means have been designed in 3GPP LTE Advanced standard to significantly enhance coverage and capacity. Huge performance gains can be achieved through increasing nodes density with the introduction of small cells, in a concept called Heterogeneous Network (HetNet). Self-Organizing...
Since their launching as voice only networks, mobile communication networks have witnessed a perpetual evolution. In the last years, the attention was addressed to high data rate networks. The lately 3GPP released LTE-Advanced network was the first to completely fulfill 4G requirements. However, performance gains remain limited due to severe interference levels. This paper is a survey upon the evolution...
Mobile communication systems have evolved considerably in recent years encouraging the deployment of multiple systems or multi-cellular technology. Quality of service (QoS) offered to mobile users improves from one system to another for example 4G systems, offer better QoS than that offered by 3G and 3.5G systems. In addition, 4G systems such as LTE (Long Term Evolution) can expand cellular coverage...
Cross-layer design is becoming a popular design methodology for the IP-based next-generation wireless systems 3G/4G. Several cross-layer methods are emerging to enhance the performance of the applications and achieve better Quality of Service (QoS) support. Through these methods, the refined wireless systems are expected to gain significant performance improvement and obtain extended functionality...
