QoS Support for Multi-user Sessions in IP-based Next Generation Networks

Abstract

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 over heterogeneous and mobile networks. MUSC uses the self-organized principle to coordinate QoS mapping and QoS adaptation mechanisms with mobility and resource allocation controllers, allowing the adaptation of a session to the current network conditions and the dynamic selection of the suitable network service class to map the session. MUSC minimizes the blocking probability, optimizes the usage of network resources and keeps sessions with an acceptable quality of experience.

Dynamic and scalable provisioning in wireless mesh networks to efficiently support multi-user killer-applications with high-demand of resources

“…• AC Mapping: Responsible for mapping the session´s QoS requirements in the most appropriate IEEE 802.11e AC (detailed in [9]). This scheme chooses the most suitable AC to a requesting session by mapping the QoS parameters provided during the request for reestablishment of the session and the list of ACs available in the wireless link, with its current QoS abilities;…”
