    Enriched IPTV Services Personalization

    The advances in IPTV (Internet Protocol TeleVision) technology enable new user-centric and interactive TV model, in which context-awareness is promising in making users' interaction with the TV dynamic and transparent. This paper deals with the problem of achieving user-centric personalized IPTV services applying context-awareness. The authors present a solution for...

    Adding Self-Scaling Capability to the Cloud to Meet Service Level Agreements

    Cloud computing raises many issues about Virtualization and Service-Oriented Architecture (SOA). Topics to be addressed regarding services in Cloud computing environment include contractualization, monitoring, management, and autonomic management. Cloud computing promotes a \"Pay-per-use\" business model. It should enable to reduce costs but requires flexible services than can be adapted, e.g.,...

    Network Capacity Enhancement of OFDMA System Using Self-Organized Femtocell Off-Load

    As plug-and-play devices, femtocells are expected to be self-managed, empowered by self-organization functionalities. This paper presents a Self-Organizing Networks (SON) process for off-loading macrocell traffic towards Open Subscriber Group (OSG) femtocells. The off-loading process comprises two SON functionalities: the first configures the femtocell transmitted pilot power, which depends on the...

    Impact of Peer-to-Peer Applications on Wide Area Network Traffic: An Experimental Approach

    To evaluate the impact of peer-to-peer applications on traffic in wide area IP networks, authors analyze measurements from a high speed backbone link carrying TCP traffic towards several ADSL areas. The first observations are that the prevalent part of traffic is due to peer-to-peer applications (almost 80% of total traffic)...

    Comparing Flow-Aware and Flow-Oblivious Adaptive Routing

    This paper compares two approaches to realizing adaptive routing in the Internet: flow-oblivious multi-path routing using optimal end-to-end congestion control and flow-aware routing using fair queueing to share bandwidth on one or several paths. Multi-path congestion control provides ideal performance, assuming protocols can be designed to approximate the optimal fluid...

    Modulation Diversity in Wideband In-Home PLC

    The power line channel is characterized by a multi-path behavior. A direct consequence is that Multi-Carrier Modulation (MCM) is generally retained for Power Line Communication (PLC). In addition to OFDM, or equivalently DMT, Wavelet OFDM and OFDM/OQAM have been recently proposed for PLC transmission. In fact, every scheme has its...

    HS-OQAM PLC: Long Filter or Equalizer?

    This paper addresses a theoretical analysis on OFDM/OQAM based transmission in PLC. The authors reveal that Inter-Carrier Interference (ICI) may be a predominant factor to limit the performance comparing with inter-symbol interference (ISI) when the channel has frequency selective behavior. Thus, for the filter design task, more attentions should be...
