Attempts by the research community to meet expectations arising from future Internet systems, and specifically to provide Quality of Service (QoS) for multimedia multi-user sessions, have resulted in mechanisms such as MultiUser Aggregated Resource Allocation (MARA). Its results have been promising, mainly because it drastically reduces signaling and processing overhead, despite its limitations in...
Envisioning to meet the expectations arising from the Future Internet, and specifically to provide efficient Quality of Service (QoS) support for multimedia multi-user sessions, the attempts by the research community have resulted in mechanisms such as Multi-User Aggregated Resource Allocation (MARA). The MARA mechanism adopts an over-provisioning centric strategy to control surplus class-based bandwidth...
With the rapidly increasing interest of citizens and businesses in multimedia group services, personalization, context- awareness and seamless mobility, the communication can no longer be limited to high speed network or devices. In future scenarios, context-aware services and multicasting will together drive a new trend, since context-awareness can exploit situations in which users share the same...
The great demand for real-time multimedia sessions encompassing groups of users (multi-user), associated with the limitations of the current Internet in providing quality assurance, has raised challenges for defining the best mechanisms to deploy the next generation of networks (NGN). There is a consensus that an efficient and scalable provisioning of network resources is crucial for the success of...
The emerging of quality of service (QoS)-enabled broadband wireless access technologies brings internetworking facilities by allowing the development of systems with high speed communications as well as service differentiation and bandwidth guarantees for communication sessions. The end-to-end QoS control in heterogeneous environments, where networks may be composed of links with different bandwidth...
