This work deals with the satisfaction of the quality of experience (QoE) requirements in the perspective of the emerging future Internet framework. The evolution of the Internet is pointing out its limitations, which are likely to hinder its potential. In this respect, this paper introduces an innovative approach to cope with some key limitations of the present communication networks. In particular,...
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...
Cloud computing is a key enabler for the development and deployment of large-scale IoT service platforms. The integration into such platforms of different sensing and actuating systems will imply the availability of many similar IoT services with common functionalities though with different QoS and cost. A cloud-based IoT platform can then benefit from implementing QoS-aware service selection algorithms...
Long-Term Evolution (LTE) has now become the leading candidate for facilitating interoperability and information sharing among different types of first responders, in what has come to be commonly known as Public Safety Networks (PSNs). However, research has shown that the bandwidth assigned to these networks will not be sufficient to support the offered load and the Quality of Service (QoS) requirements...
In order to manage the exponential growth of traffic in mobile network environments and the increasing requirements on bandwidth, Quality of Service (QoS) and mobility, the Mobile Network Operators (MNOs) infrastructure has to provide for an appropriate traffic distribution among the available networks. This paper proposes a new real-time traffic distribution framework, called Black Rider, which is...
Clouds and data centres are significant consumers of power. There are however, opportunities for optimising carbon cost here as resource redundancy is provisioned extensively. Data centre resources, and subsequently clouds which support them, are traditionally organised into tiers; switch-off activity when managing redundant resources therefore occurs in an approach which exploits cost advantages...
The IMS Network QoS Architecture approach for monitoring and supervision services in the IMS offers innovative solutions for QoS management in real time. These solutions enable the integration of automatic correcting mechanisms for QoS deterioration, depending on network conditions and customer importance. However, the correction operation is costly in terms of resources and execution time. Face to...
Handling the dynamics of future service-based distributed systems in real-time is a complex problem; a number of state transitions or reconfigurations take place that must be handled in real-time; this requires to impose some bounds to the structure of the system to ensure timely operation. We present a model for real-time reconfiguration based on a service model using the concept of service implementations...
One of the major challenges for real-time applications over next-generation heterogeneous access networks is the vertical handoff. Such applications require fast and efficient handover that realize service continuity and seamless mobility preserving the security and the QoS. In this paper we propose a new seamless vertical handover solution performing fast authentication while guaranteeing the QoS...
