  1. 6. Resilient routing and spectrum assignment in Elastic Optical Networks under Dynamic Traffic

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Christian Thiessen; [2014]
    Nyckelord :;

    Sammanfattning : Transparent Elastic Optical Networks (EON) are seen as a promising solution for future optical transport networks to keep up with internet traffic growth, as they allow provisioning connections with different bandwidth requirements in an efficient way. To achieve high spectrum efficiency in these networks, making good Routing, Modulation and Spectrum Assignment (RMLSA) decisions is essential. LÄS MER

  3. 7. Analyzing Wavelength Conversion and Traffic Grooming in Optical WDM Networks

    Magister-uppsats, Informationskodning; Tekniska högskolan

    Författare :Wajid Ali; Shahzaan Mohammed; [2013]
    Nyckelord :;

    Sammanfattning : Wavelength conversion and traffic grooming have been among the most researched areas and technologies of importance in optical networking. Network performance improves significantly by relaxing the wavelength continuity constraint using wavelength converters and by improving the wavelength utilization using traffic grooming. LÄS MER

  4. 8. Distance Adaptive Shared Path Protection for Elastic Optical Networks under Dynamic Traffic

    Master-uppsats, KTH/Programvaruteknik och Datorsystem, SCS

    Författare :Faik Aras Tarhan; [2013]
    Nyckelord :;

    Sammanfattning : Recently, the internet traffic demand has been compoundly rising up as a result of the increase in the number of users as well as data demand per user. That is why, Elastic Optical Networks (EONs), which employ Orthongonal Frequency Division Multiplexing (OFDM) , have been proposed to scale the demands by efficiently utilizing the spectrum as they provide finer spectrum granularity and distance adaptive modulation formatting.

  5. 9. Performance Analysis of Channel Allocation Schemes in WiMAX

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Muhammad Rehan Usman; Johar Iqbal; Fahad Razzaq; [2009]
    Nyckelord :WiMAX; OFDMA; RCS; NPS; DCA; FCA; Handovers;

    Sammanfattning : Today many cellular networks are working in parallel. For instance Global System for Mobile Communication (GSM), Universal Mobile Telecommunication System (UMTS) and Worldwide Interoperability for Microwave Access (WiMAX) etc. All of these technologies are based on cellular networks. Cellular networks are comprised of cells. LÄS MER

  7. 10. Multi-Cell Admission Control for WCDMA Networks

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Gustavo Azzolin de Carvalho Pires; [2006]
    Nyckelord :WCDMA; Elastic Traffic; Admission Control; Rate Control; Blocking Probability; Outage Probability;

    Sammanfattning : It has long been recognized that in multi-cell WCDMA networks the admission of a new session into the system can have undesirable impact on the neighboring cells. Although admission control algorithms that take into account such multi-cell impact have been studied in the past, little attention has been paid to multi-cell admission and rate control algorithms when traffic is elastic.
