Cloud computing offers the elasticity features by dynamically resizing the infrastructure in response to changes in workload demands to meet performance guarantees and minimize costs. In the last decade, a large body of work has been done in the area of horizontal elasticity, while only few research efforts addressed vertical elasticity. This paper develops a vertical elasticity controller for cloud-based...
Argumentation has been proved as a simple yet powerful approach to manage conflicts in reasoning with the purpose to find subsets of “surviving” arguments. Our intent is to exploit such form of resolution to support the administration of security in complex systems, e.g., in case threat countermeasures are in conflict with non-functional requirements. The proposed formalisation is able to find the...
In this paper, we propose a method to construct scalable sensor data stream delivery system that guarantees the specified QoS of the delivery, i.e. Total reachbility to destinations even in a heterogeneous churn situation of the delivery server resources (nodes). There were some P2P-based methods to construct scalable and efficient sensor data stream system that accommodates different delivery cycles...
The paper describes an innovative and fully cognitive approach which offers the opportunity to cope with some key limitations of the present telecommunication networks by means of the introduction of a novel architecture design in the perspective of the emerging Future Internet framework. Within this architecture, the Quality of Experience (QoE) Management functionalities are aimed at approaching...
Quality of Experience (QoE) is a wide concept including user perception, behavior and expectations as well as application and network performances. The Internet of the future should be able to increase the QoE offered to the users, also in relationship with their commercial profiles. This paper presents an innovative approach, based on game theory, which, according to the feedback of QoE, is able...
current internet infrastructure is still configured and managed manually or adopting a limited level of automation. The Future Internet aims to provide the network resources as a service to ease the process of automatic designing, controlling and supervising the telecommunication infrastructure. A key enabler of the Future Internet is the virtualization of the available resources and of the related...
Internet evolution follows the customer needs, each algorithm, protocol, architecture, equipment, functionality succeeded when the users perceived a real benefit in using it. Taking into account the impact of customer experience when designing promising and future proof technologies is essential. In this paper we investigate how it is possible to control network resources on the base of the Quality...
Network virtualization techniques allow for the coexistence of many virtual networks hosted in a same substrate network. Virtual router migrations allow for resource consolidation with the consequence to reduce the power consumption in low traffic periods. Unfortunately virtual router migrations have the effect of degrading the Quality of Service during the downtime in which the router is not able...
In this paper, we present a framework for evaluating the QoE of a service that includes functional and non-functional service requirements. Non-functional requirements are classified into objective, subjective, and business parameters that affect Quality of Service (QoS), Quality of Experience (QoE), and Quality of Business (QoBiz), correspondingly. As those metrics have a strong dependency between...
Consumer acceptance is of great interest in the adoption of novel multimedia products and services. A number of factors can greatly influence the customer experience during a video session, impacting the acceptability of the product or service. Factors such as the Technical Quality (TQ) which covers the technical aspects of the signal quality can be controlled from the network provider. On the other...
Quality of Experience (QoE) has emerged as the key performance metric to evaluate end-user service quality perception. We propose a system for video and web QoE assessment in LTE networks that we call QoE Analytics system. We build the proposed system and run it on a LTE network and successfully estimates QoE metrics per UE in real-time by inspecting user plane data on S1 interface without any QoE...
Users run multiple applications simultaneously on single mobile device (MD) like mobile phone, tablet etc.. Utility and importance of different applications are not same and relative value depends on individual user. But in Internet architecture, available bandwidth is shared by applications equally. In wireless connection, fluctuation of bandwidth is common event and all applications are affected...
In this work, a heterogeneous cellular network with caching enabled at the small cell aggregators is analyzed. The caching technology is enabled to help offload some of the popular traffic requests onto the cache. In this framework, a network congestion game is formulated to study the evolution of traffic when every user as an independent decision maker decides its choice of communication, i.e, via...
Content Delivery Networks have gained a popular role among application service providers (ASPs) and infrastructural companies. A CDN is an overlay network that gives more control of asset delivery by strategically placing servers closer to the enduser, reducing response time and network congestion. Many strategies have been proposed to deal with aspects inherent to the CDN distribution model. Though...
This paper presents the remote control of a mobile robot via internet. To solve the problem of delay time which is unpredictable, direct teleoperation architecture is proposed. This architecture allow s us to minimize the trajectory error of the robot movement which is controlled via the internet. This work also demonstrates the use of virtual reality in the context of the remote control. Virtual...
This survey was done due to high non-satisfaction level of a usage system, known as e-Aduan, an electronic system used to generate electrical, mechanical, telecommunication, civil, landscape, infrastructure or facilities management complaint from user. e-Aduan is subscribed and handled by Universiti Teknologi Mara (UiTM), for all developers of 7 Private Fund Institution (PFI) Campuses located throughout...
This paper describes advanced networking technologies that support high quality video and image communications. We focus on maintaining Internet compatibility and extracting the merit of ATM technologies. A concept of Global Mega-media Network (GMN) is introduced as the future multimedia network. As part of work associated with GMN, an overview of AMInet project and some of the promising technologies...
This paper uses the Technology Acceptance Model (TAM) to identify the factors influencing citizens' acceptance and intention to use e-government in Sudan. Specifically, a survey questionnaire was used to collect responses from a sample of (292) participants using the Electronic Passport and National ID services. Results from this study showed that the quality of services and advertising have significant...
There are several challenges for enabling an Internet that is universally available and accessible to all. These challenges can be overcome by innovations in technology, economics and regulation/policy. Over the last few years the smart data pricing community have proposed several innovative pricing solutions which have the potential for reducing the cost of Internet access. However, it is imperative...
The classification of Internet traffic is of interest in areas like differentiated services and network security. Such classification is usually done using the packet header field of ‘port number’. However, recent developments in networking techniques have rendered the port numbers unreliable for this purpose. Our scheme of classification uses the distribution of packet sizes in a buffer or collected...
