“…The latter would require additional control and coordination in the network and MN for optimal performance. One possible approach for extending the proposed system architecture to support coordination and scalability in the network-side control for the management of multi-access networks has already been presented in Kliazovich et al [96]. Related solutions are also being detailed in follow-up projects.…”

“…The proposed solution is essentially based on the DCMF concept proposed by Mäkelä et al [95]. Kliazovich et al [96] extending the DCMF to support hierarchical decision-making required in multi-operator environments for better scalability, but these extensions are left for future work and not considered in this thesis.…”

“…The latter approach is adopted for prototyping in this dissertation. The interested reader is directed to the numerous publications related to the TRG concept, prototype performance evaluation, and its use in heterogeneous networking scenarios, including, for example, [49,[92][93][94][95][96]. In addition, some of the studies include the co-use of MIH and TRG in providing the required cross-layer signaling for optimized video transfer [20,97].…”

“…Located in the wired network, the NIS shares the same analogy with the standard information services, such as the IEEE 802.21 remote MIHF communication and MIIS as well as the 3GPP ANDSF without the restriction to handover management-related information. In larger networks, the NIS may also be deployed hierarchically for scalability [96].…”

This dissertation studies the impact of heterogeneous wireless networks on the design and implementation of mobile video streaming services. The aim is to enable Quality of Service (QoS) sensitive video streaming services to take full advantage of the access diversity of heterogeneous networks in order to optimize their operation in terms of quality and efficiency of network resource usage. This nevertheless requires support beyond the layered communication architecture of today's Internet.The thesis proposes an architecture for end-to-end cross-layer signaling and control for video streaming systems. The architecture supports extensive context information transfer in heterogeneous networks; thus, enabling the efficient management of video stream adaptation and user terminal mobility in a diverse and dynamic network environment. This thesis also studies and proposes cross-layer enhancements for adaptive video streaming and mobility management functions enabled by the cross-layer architecture. These include cross-layer video adaptation, congestion-triggered handovers, and concurrent utilization of multiple access networks in the video stream transport. For the video adaptation and multipath transmission, the flexible adaptation and transmission capabilities of the novel scalable video coding technology are used. Regarding the mobility management, the proposed solutions essentially enhance the handover decision-making of the Mobile IP protocol to better support QoS-sensitive video streaming. Finally, the thesis takes a holistic view on the application adaptation and mobility management, and proposes a solution for coordinated control of these two operations in order to achieve end-toend optimization.The resulting mobile video streaming system architecture and the cross-layer control algorithms are evaluated using network simulations and real prototypes. Based on the results, the proposed mechanisms can be seen to be viable solutions for improving video streaming performance in heterogeneous wireless networks. They require changes in the communication end-points and the access network but support gradual deployment. This allows service providers and operators to select only a subset of the proposed mechanisms for implementation. The results also support the need for cross-layer signaling and control in facilitating efficient management and utilization of heterogeneous wireless networks.
