Mobility management for multi-user sessions in next generation wireless systems
Cerqueira, Eduardo; Veloso, Luis; Neto, Augusto; Curado, Marilia; Monteiro, Edmundo; Mendes, PauloMobility management and ubiquitous access for real-time multi-user sessions with Quality of Service (QoS) support are major requirements to the success of next generation wireless systems. In this context, Multi-User Session Control (MUSC) is proposed to allow fixed and mobile users to access multi-user sessions ubiquitously, while providing QoS mapping, QoS adaptation and connectivity control in heterogeneous ...
QoS Support for Multi-user Sessions in IP-based Next Generation Networks
Cerqueira, Eduardo; Veloso, Luis; Neto, Augusto; Curado, Marilia; Monteiro, Edmundo; Mendes, PauloAbstract A combined control of multimedia quality level, mobility and allocation of network resources is essential for the success of next generation mobile networks. In this context, this article presents the Multi-user Session Control (MUSC) solution to control the quality level of multimedia sessions shared by multiple-users, providing Quality of Service (QoS) mapping and QoS adaptation for those sessions o...
Multi-Class Measurement Based Admission Control for a QoS Framework with Dynami...
Bohnert, Thomas; Monteiro, EdmundoThe advent of a Premium Service (PS) featuring Internet is still pending, mainly due its difficult deployment. But do we really need Quality of Service like PS? Likely no. We are therefore investigating an alternative QoS model, which is more flexible to deploy at the expense of looser QoS guarantees. We call it a Better-than-Best-Effort (BBE) service. What distinguishes our approach from traditional ones is dy...
EuQoS approach for resource allocation in Ethernet networks
Carmo, Maxweel Silva; Silva, Jorge Sá; Monteiro, EdmundoAlthough the equipment currently available for Ethernet LANs provides basic quality of service (QoS) capabilities, as the ability of prioritizing traffic flows, it does not support more complex mechanisms like admission control or the ability of participating in a signalling process. This paper presents a survey on the QoS support and on resource allocation for LAN Ethernet networks, and describes a new proposa...
How to increase the efficiency of receiver-driven adaptive mechanisms in a new ...
Mendes, Paulo; Schulzrinne, Henning; Monteiro, EdmundoReceiver-driven adaptation allows streaming of multicast multimedia content to different receivers across networks with heterogeneous characteristics, such as different resource availability. However, receivers are only encouraged to adapt if network providers guarantee a fair distribution of bandwidth and also the punishment of receivers that do not adjust their rate in case of congestion. Therefore, we define...
