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...
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...
An emerging usage is to rely on mobile devices (Smartphones or tablets) for large-scale events. They can be used for many applications like live voting or chatting, but also to access all the data related to an event. However, in such case, handling mobile devices trying to access data simultaneously is difficult. A Wi-Fi access point can only handle a limited amount of devices. Current solutions,...
Due to dynamic wireless network conditions and heterogeneous mobile web content complexities, web-based content services in mobile network environments always suffer from long loading time. The new HTTP/2.0 protocol only adopts one single TCP connection, but recent research reveals that in real mobile environments, web downloading using single connection will experience long idle time and low bandwidth...
Mobile Edge Computing (MEC) provides mobile and cloud computing capabilities within the access network. Network Functions Virtualization (NFV) leverages standard IT Virtualization technology to decouple the network functions from the underlying physical infrastructure. Basing on the ICT demand, MEC can be consolidated into NFV, as a network element within access network. This paper presents an architecture...
Mobile Edge Computing (MEC) aims to provide mobile and cloud computing capabilities within the radio access network, and emphasizes the openness of the internet which can transfer the real-time radio network information into context-related services. In this article, we research the state-of-the-art technology of mobile and cloud convergence, then propose WiCloud, a MEC platform, which integrates...
Recently, mobile video streaming services become very popular. MPEG-DASH is one of the streaming schemes used for the service. In this method, a mobile terminal tries to download video chunks from a streaming server by estimating the available bandwidth of the underlying network. However, it is very difficult to estimate the available bandwidth because this method is working as an OTT (over the top)...
Smart Internet Devices (SIDs) particularly Smartphones are soon turned to be super computers, while the restricted battery timing is a focused issue which hinders the steady meeting expectations yield of these devices. In addition, various sensors, high resolution LCDs, wireless interfaces, GPS and other advanced features drain battery quickly, thus, shrinking the operational time. Subsequently, increasing...
Web caching has been used extensively to enhance web delivery to clients by minimizing the latency perceived by clients, reducing network bandwidth usage, reducing power consumption and improving the network quality of service. Caching performance can be improved by implementing an efficient replacement policy to be used for proper cache replacement. In mobile networks, the movement of users presents...
Consumption of multimedia content is moving from a residential environment to mobile phones. Optimizing Quality of Experience -- smooth, quick, and high quality playback -- is more difficult in this setting, due to the highly dynamic nature of wireless links. A key requirement for achieving this goal is estimating the available bandwidth of mobile devices. Ideally, this should be done quickly and...
Since commercialization of the Internet in mid-1990, human culture has changed dramatically due to booming of innovative online services. To cope with demands of network service providers to effectively and efficiently deliver contents and services to their clients, content distribution network technologies have been developed. These technologies have been optimized to transfer data from servers to...
Mobile data traffic is increasing rapidly and wireless spectrum is becoming a more and more scarce resource. This makes it highly important to operate the mobile network efficiently. In this paper we are proposing a novel lightweight measurement technique that can be used as a basis for advanced resource optimization algorithms to be run on mobile phones. Our main idea leverages an original packet...
Smart phones are ubiquitous nowadays and have taken over the bulk data transfers in mobile networks. The next generation phones are even more powerful to handle voice, video and data catering real time multimedia experience. Unfortunately, the increase in service provider capacity has not kept up with the user demand for more bandwidth. It is becoming very expensive for service providers to cater...
The rapid traffic growth fueled by mobile devices spread and high speed network access calls for substantial innovation at network layer. The content-centric nature of Internet usage highlights the limitations of the host-centric model in coping with dynamic content-to-location binding, mobility, multicast, multi-homing, etc. If transmission capacity speedups in the backhaul may hide inefficiencies...
Information-Centric Networking (ICN) has a great potential to better support the content distribution over the future Internet. Meanwhile, users with mobile devices will also access ICN, introducing a new challenge to ICN providers to handle such mobile content requests. In this paper, a mobility and popularity-based caching strategy is proposed to increase the cache hit rate through WiFi while people...
Along with an ever-growing demand for rich video applications by a rapidly increasing population of mobile users, it is becoming difficult for the Internet backbone to cope with a constantly increasing mobile traffic. Though multi-source mobile streaming (MS2) was proposed to solve the bottleneck issue of the Internet backbone considering simultaneous multiple low streaming rate transmissions to mobile...
Knowledge of the queue length of the bottleneck link has many potential applications such as congestion control, traffic engineering, traffic policing, content adaptation, QoS monitoring and provisioning, etc. A recent work proposed a new Sum-of-Delay with Timestamp (SoD-TS) algorithm which can accurately estimate queue length in mobile networks with both bandwidth variations and uplink delay variations...
Over the last few years, the importance of cloud services for file synchronization has been increasing. With the release of network enabled cameras like Google Glass the trend of synchronizing new photos with the cloud has emerged as an important new use case for mobile networks. Multiple stakeholder are interested in optimizing this synchronization process according to different orthogonal metrics...
In mobile cloud computing (MCC) systems, the resource in both the cloud and the mobile network should be carefully managed. Cloud resource management and radio resource management have traditionally been addressed separately in previous works. In this paper, we propose to jointly study dynamic cloud and radio resource management so as to improve end-to-end performance of adaptive video transmissions...
Recently the mobile cloud computing (MCC) are increasingly emerging as an efficient environment to provide lots of effective and convenient mobile services for our daily life. Different from cloud computing, MCC dominant the properties of mobile devices rather than PC such as mobile network 3G/4G, limited hardware resources, mobility, etc. Therefore, Quality of Experience (QoE) on mobile devices plays...
