Founded in 2005 YouTube has became the most fast growing stream service, that has a great impact on the internet traffic distribution. Thus understanding YouTube's characteristics is crucial to network providers. In this survey we are going to present the factors that impact user's satisfaction, in other meaning the impact on the Quality of experience(QoE). Furthermore we will discuss how to determine...
Inter-Cell Interference Coordination (ICIC) techniques are proposed as solutions to alleviate the negative impact of interference on system performance, while enhancing the provided Quality of Service (QoS). Typically, the available bandwidth is divided into inner and edge sub-bands. Users are also classified into interior and edge users. The available resources in each zone are exclusively allocated...
Available smartphone« and smart objects can use short range connections like Wi-Fi and Bluetooth as a communication technique to exchange information with nearby devices. Those techniques are used in cases of absent end-to-end connection such as in Delay Tolerant or Opportunistic Networks. The study of message transmission processes and contact information in such networks has gained more attention...
While the bandwidth and latency improvement of both WiFi and cellular data networks in the past decade are plenty evident, the extent of signal strength fluctuation and network disruptions (unexpected switching or disconnections) experienced by mobile users in today's network deployment remains less clear. This paper makes three contributions. First, we conduct the first extensive measurement of network...
In the next generation mobile network, the concept of virtual network slice (VNS) has been proposed to facilitate the building of a dedicated and customized logical network with isolated resources, which can be defined as a subset of network resources allocated to a virtual operator or service provider. Each VNS is associated with a virtual network function forwarding graph (VNF-FG) to accomplish...
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...
Over the past few years, Mobile Ad hoc net-works(MANETs) have gained importance in mission critical environments. Software defined radios(SDRs) have provided MANETs a platform for using Narrowband networking wave-form(NBNW) for concurrent voice and data transmissions. Traditional TDMA MAC protocols are not appropriate for such applications. In this paper we have proposed a distributed TDMA slot assignment...
The Manet or Mobile Ad-Hoc Networks are capable of forming wireless networks with different topologies. The radios which form the network uses a specific band, data rate and frequency. The paper focuses on the implementation of intelligent Mobile Ad-hoc NETwork (iMANET) in which wireless networks are established using reconfigurable radios so that intelligent networks can be formed. The nodes involved...
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 (smartphones, mobile hotspots, vehicular infotainment systems). The highly dynamic nature of such scenarios calls for continuous monitoring and measurement of the network, and possibly cross-layer management of network applications. A recent...
Accessing online social media content on underground metro systems is a challenge due to the fact that passengers often lose connectivity for large parts of their commute. As the oldest metro system in the world, the London underground represents a typical transportation network with intermittent Internet connectivity. To deal with disruption in connectivity along the sub-surface and deep-level underground...
Upload and download traffic often coexist in mobile networks. However, TCP download throughput could be substantially degraded by upload traffic even if the downlink is not the bottleneck. Previous works such as RSFC and TCP-RRE can substantially improve TCP download throughput in the presence of concurrent TCP upload flows, albeit at the expense of significantly degraded upload throughput performance...
In this paper, we study the energy-efficient resource allocation in software-defined mobile networks with mobile edge computing and caching. With the introduction of caching and computing functions in mobile networks, content sources need to be selected according to the distribution of contents in caches, the capability of computational resources and the status of networks. Moreover, the network needs...
The management of radio congestion in the control channel is one of the active research areas in Vehicular Ad-hoc Networks (VANETs). Many congestion control protocols have already been proposed to ensure an optimal management of the radio control channel. LIMERIC is a well-known congestion control protocol which was adopted by the current ETSI standardization process to be applied in the future deployment...
The Mobile Cloud Network is an emerging cost and capacity heterogeneous distributed cloud topological paradigm that aims to remedy the application performance constraints imposed by centralised cloud infrastructures. A centralised cloud infrastructure and the adjoining Telecom network will struggle to accommodate the exploding amount of traffic generated by forthcoming highly interactive applications...
The message delivery ratio of mobile opportunistic networks strongly depends on the transmission time, which is closely related either to the mobility of users and to the communication properties of the mobile devices. A larger radio transmission range allows longer contact durations, improving the message dissemination. Furthermore, user mobility is a crucial factor to be considered, especially when...
Software-defined networking and mobile edge caching are promising technologies in next generation mobile networks. This paper proposes to jointly optimize bandwidth provisioning and caching strategies in software-defined mobile networks considering the quality of services and limitations of resources. The proposed scheme aims at maximizing gains from dynamically managing caches and efficiently utilizing...
The quality of service for an end user is defined by the quality of the network links connecting user and service provider. There are several parameters impacting network communication links, a very important one being the available end-to-end bandwidth. Bandwidth measurements in cellular wireless networks with traffic reactive nature, nomadic end users and highly dynamic shared resources is a challenging...
The Heterogeneous Wireless Network is a hierarchical structure of different wireless networks. The wireless networks are differ in terms of network coverage, capacity, bandwidth, technology and network operator. In such an environment when a mobile terminal equipped with multiple network interfaces leaves one wireless network and connect to another different wireless network, a Vertical Handoff (VHO)...
Multi-tenancy allows diverse agents sharing the infrastructure in the 5th generation of mobile networks. Such a feature calls for more automated and faster planning procedures in order to adapt the network capacity to the varying traffic demand. To achieve these goals, Small Cells offer network providers more flexible, scalable, and cost-effective solutions compared to macrocell deployments. This...
