In this article we present a scalable VOD distribution architecture for broadband operators. The solution is based on a P2P streaming concept in which a VOD streaming session requested by a given STB (Set-Top-Box) is actually provisioned via a multisource streaming session. This solution has the advantage of scaling naturally with the number of STBs in the network. In this article we focus on efficiently translating the popularity distribution into content availability in the network.

The effects of different numbers of active systems with different traffic patterns were examined. The results obtained indicate significant variation in channel load values calculated by different stations experiencing different levels of interference. This variation leads us to question the usefulness of a single channel load measurement; hence considerable care must be taken when using and interpreting such measurements. }, keywords={IEEE802.11k, Channel Load Measurements, Interference}, author={C.

Simulation results show that our approach is more efficient than existing approaches: solutions of equivalent quality can be found in 40% of the time.

It identifies that retransmission of all data on an alternate path with the path failure detection threshold set to zero performs best in symmetric path conditions but its performance degrades acutely in asymmetric path conditions even when the alternate path delay is shorter than the primary path delay. It illustrates that retransmission of all data on the same path with the path failure detection threshold set to one or zero gives the most stable performance in all path configurations.}, </bibtex> <bibtex> @article { type={article }, cite={222}, title={Forward Error Correction Strategies for Media Streaming over Wireless Networks}, journal={IEEE Communications Magazine}, volume={46}, year={2008}, month={01/2008}, pages={72-79}, publisher={IEEE}, abstract={The success of next-generation mobile communication systems depends on the ability of service providers to engineer new added-value multimedia-rich services, which impose stringent constraints on the underlying delivery/transport architecture. The reliability of real-time services is essential for the viability of any such service offering. The sporadic packet loss typical of wireless channels can be addressed using appropriate techniques such as the widely-used packet-level Forward Error Correction. In designing channel-aware media streaming applications, two interrelated and challenging issues should be tackled: accuracy of characterizing channel fluctuations and effectiveness of application-level adaptation. The first challenge requires thorough insight into channel fluctuations and their manifestations at the application level, while the second concerns the way those fluctuations are interpreted and dealt with by adaptive mechanisms such as FEC. In this article we review the major issues that arise when designing a reliable media streaming system for wireless networks.}, </bibtex> <bibtex> @inproceedings { type={inproceedings }, cite={224}, title={Planning Base Station and Relay Station Locations in IEEE 802.16j Multi-hop Relay Networks}, booktitle={Proc. 2nd IEEE Broadband Wireless Access Workshop, colocated with IEEE CCNC 2008}, year={2008}, month={01/2008}, abstract={In this paper, a problem formulation for determining optimal node location for Base Stations (BSs) and Relay Stations (RSs) in relay-based 802.16 networks is developed.

abstract={An e-learner’s Quality of Experience (QoE) is informed by previous experiences as a learner, a user of computer/web-based systems, and a customer. This paper surveys different concepts for Quality of Experience (QoE) from different areas such as psychology, internet marketing, web engineering, systems and product development as well as philosophy of education. They are summarized into a proposal for a definition of Learner QoE in adaptive multimedia e-learning systems. A number of factors are identified that are likely to impact on QoE. We propose a <st1:place w:st="on">Delphi</st1:place> study to be used to provide an initial ranking of the importance of these factors. Additional user testing will be required to confirm the findings of this study.

The study finds that the introduction of transparent mode relays cannot deliver improved throughput for a substantial part of the coverage area of a Base Station (BS) – only approximately half of the total area covered by the BS can benefit from throughput enhancement. Further, the study shows that 802.16j based systems require significant signalling overhead, with almost twice that of 802.16e in the cases studied.

These conditions are satisfied at runtime by services of the underlying platform, thus ensuring that the context in which components run exhibits properties that allow them to operate correctly. Depending on how components call each other, it is possible that satisfying such conditions lead to problems such as reduced performance due to redundant service execution, or permanent errors (composition mismatches), due to incompatible boundary conditions. Currently, the semantics of these boundary conditions are expressed in natural language only, making it impossible to incorporate them into an automatic analysis tool. Furthermore, early understanding of how components call each other would be necessary, but it is currently difficult to achieve by means of a tool, as the method dispatch rules in a component system differ from the dispatch rules of the programming language(s) in which they were developed. We have developed a metamodel, $${\mathbb{M}}$$ , for describing boundary conditions, an analysis method, $${\mathbb{A}}$$ , and a static component-level call graph extraction method for EJB applications, CHA EJB . $${\mathbb{A}}$$ uses $${\mathbb{M}}$$ models to analyze inter-component call graphs, and thus detect problems such as composition mismatches or redundancies, thus allowing for remedial action to take place. We present $${\mathbb{M}},{\mathbb{A}}$$ and CHA EJB in this article, show that $${\mathbb{A}}$$ produces correct results, and describe a prototype analysis tool implementing the three, which we used to validate our approach on two popular EJB applications. }, keywords={Software components - Contextual composition - Static analysis - Enterprise Java }, author={Trofin,M. and Murphy,J.}, </bibtex> <bibtex> @proceedings { type={proceedings }, cite={406}, title={SCTP Switchover Performance Issues in WLAN Environments}, year={2008}, publisher={Performance Engineering Lab}, address={Las Vegas,Nevada}, abstract={The increased number and diversity of underlying}, </bibtex> <bibtex> @proceedings { type={proceedings }, cite={478}, title={Service quality improvement based on Network Attachment Subsystem extensions and Service Enhancement Function - Mesh Networks as an example}, year={2008}, abstract={...}, keywords={WMN, Security}, author={Andreas Roos and Sebastian Robitzsch and Bangnan Xu and Sabine Wieland and Andreas Schwarzbacher}, </bibtex> <bibtex> @proceedings { type={proceedings }, cite={477}, title={Wireless Mesh Network Coverage with QoS Differentiation for Rural Areas}, year={2008}, abstract={...}, keywords={WMN}, author={Mathias Kretschmer and Sebastian Robitzsch and Christian Niephaus and Karl Jonas and Gheorghita Ghinea}, </bibtex>
