Concerning video transmission on the Internet, we present a model for estimating the subjective quality from objective measurements at the transmission receivers and on the network. The model reflects the quality degradation subject to parameters like packet loss ratio and bit rate and is calibrated using the results from subjective quality assessments. Besides the model and the calibration, the main achievement of this paper is the model's validation by implementation in a monitoring tool. It can be used by content and network providers to help swiftly localise the causes of a possibly poor quality of experience (QoE). It also can help content providers make decisions regarding the adjustment of vital parameters, such as bit rate and other error correction mechanisms.

AbstractPurpose -Coexistence of various wireless access networks and the ability of mobile terminals to switch between them make an optimal selection of serving networks for multicast groups a challenging problem. Since optimal network selection requires large dimensions of data to be collected from several network locations and sent between several network components, the scalability can easily become a bottleneck in large-scale systems. Therefore, reducing data exchange within heterogeneous wireless networks is important. The paper aims to discuss these issues. Design/methodology/approach -The authors study the decision-making process and the data that need to be sent between different network components. To analyze the operation of the wireless heterogeneous network, the authors built a mathematical model of the network. The objective is defined as a minimization of multicast streams in the system. To evaluate the heuristic solutions, the authors define the upper and lower bounds to their operation. Findings -The proposed heuristic solutions substantially reduce the usage of bandwidth in mobile networks and exchange of information between the network components. Originality/value -The authors proposed the approach that allows network selection in a decentralized manner with only limited information shared among the decision makers. The authors studied how different sets of information available to decision makers influenced the performance of the system. The work also investigates the usage of multiple paths for multicast in heterogeneous mobile environments.

Mobile and multi-access devices have become commonplace today. In this context, nodes have multiple interfaces that can form the foundation for the always best connected paradigm. Mobile IPv6, the staple mobility management technology for the Internet, enables nodes to roam between different networks while minimising session disruption due to handovers. However, in standard MIPv6, a mobile node can register only a single IP address as its Care-of-Address (CoA), therefore the multiplicity of network interfaces may be managed suboptimally while simultaneous multi-access is not possible. Recently, MIPv6 has been extended with a much-anticipated feature, namely Multiple Care-of Address (MCoA) registration. MCoA allows a MIPv6 node to register all active addresses configured on the respective interfaces and then use them at will, possibly in an alternating fashion as well as simultaneously. MCoA is anticipated to improve the performance of multimedia applications, yet this is still to be quantified. This paper provides a first answer to this question. In particular, we employ simulation to evaluate the benefits for multimedia applications, such as VoIP and video, from the use of MCoA. We compare the MCoA results with those obtained when MIPv6 with single address registration is used based on objective multimedia evaluation metrics, such as PESQ. In addition we examine the tradeoffs between application benefits and signaling costs for the network.
