Multimedia services are rapidly growing in interest with the increase of available bandwidth on core and mobile technologies. There is a business opportunity for both adaptability and personalization of services centralized in users and their surrounding environment. Context Awareness requires the network to support mechanisms that are able to get information from the user situation as location, activity, presence, velocity, preferences, surrounding noise, etc., and triggering session modification and network control mechanisms. Context awareness provides a new trend in pervasiveness since it allows a full, but unconscious interaction between users, operators and service providers. This paper presents the results, from simulation and demonstrator implementation, of an architecture that enables context-aware and personalized multiparty multimedia content delivery, independently of the underlying access and transport technologies.

“…The QoS Architecture for Multi-user Mobile Multimedia (Q3M) [8] is one of the works that addresses this issue, introducing the Multi-service Resource Allocation (MIRA) [9] protocol, designed to control the resources of the CoS and multicast trees in a synchronized manner taking into account the problem of asymmetric routes. A centralized structure to support QoS was developed in [10], enabling QoS and mobility of multicast sessions in heterogeneous environments. More recently, new algorithms and techniques are proposed, such as the QoS mobile multicast routing based on ant colony optimization [11], which has a strong global optimization performance.…”

The demanding requirements of new real-time and mobile multimedia group-based applications (e.g. IPTV and video-conferencing) motivates the research for novel and efficient network architectures, able to fulfil service requirements and increase user experience. Multicast, despite its scalability issues, is the most suitable network technology for the delivery of multiparty content. Context-awareness is taken as a key feature in Next Generation Networks, enabling a management framework with a more comprehensive knowledge of the network, application and user. The challenge is how to use the available knowledge towards service personalization and network efficiency. This paper presents and evaluates an architecture that aims to provide personalized session content delivery to multiple mobile users, integrating different access and transport technologies. The architecture relies on an end-to-end contextaware communication framework able to dynamically react and adapt to context changes, through session and network reconfiguration. Our focus is on the transport network part, addressing a new level of scalable multiparty content delivery through the concepts of abstract multiparty trees and overlay nodes. The results show that the concept of abstract trees reduces the network reconfiguration complexity while still guaranteeing end-to-end QoS.

With the rapidly increasing interest of citizens and businesses in multimedia group services, personalization, contextawareness 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 interests and request similar services, increasing the effectiveness of session and network control. However, context-aware networks impose several challenges: any change to context, such as, location, mobility, velocity, preferences, presence, etc., can change the overall services and network environments, requiring completely restructuring of the network and multicast sessions in a very dynamic way. This dynamicity imposes scalability problems in current networks.In this paper, we present an initial future Internet architecture for context-aware network and service control, which enables the support of context-aware users and services, seamless reacting to the context changes with minimal impacts to the services and multicast control. For this purpose, we provide a network that is able to interact with context-based services, choose and change the session and network characteristics based on the context, both for the environment, user, network, and sessions. To address the dynamicity of the network, we provide the support of multicast abstract transport trees able to abstract the network changes to the running sessions transport, and limiting the impact of all the context dynamics in the user sessions.
