  1. 1. On Admission Control for IP Networks Based on Probing

    Author : Ignacio Más; Gunnar Karlsson; Wolfgang Effelsberg; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Admission control; QoS; IP networks; Telecommunication; Telekommunikation;

    Abstract : The current Internet design is based on a best-effort service, which combines high utilization of network resources with architectural simplicity. As a consequence of this design, the Internet is unable to provide guaranteed or predictable quality of service (QoS) to real-time services that have constraints on end-to-end delay, delay jitter and packet loss.

  2. 2. Coding Schemes for Relay Networks

    Author : Majid Nasiri Khormuji; Mikael Skoglund; Gerhard Kramer; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Relay networks; capacity; decode-and-forward; amplify-andforward; compress-and-forward; nonlinear relaying; noisy network coding; hybrid relaying; Telecommunication; Telekommunikation;

    Abstract : Cooperative communications by pooling available resources—for example, power and bandwidth—across the network, is a distributed solution for providing robust wireless transmission. Motivated by contemporary applications in multi-hop transmission and ad hoc networks, the classical three-node relay channel (RC) consisting of a source–destination pair and a relay node has received a renewed attention.

  3. 3. On Deterministic Models for Wireless Networks

    Author : Nicolas Schrammar; Mikael Skoglund; Olav Tirkkonen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication theory; Telekommunikationsteori;

    Abstract : Wireless communication is commonly modeled as a stochastic system. This is justified by the fact that the wireless channel incorporates a number of stochastic effects including fading, interference and thermal noise. READ MORE

  4. 4. Design, analysis and simultion for optical access and wide-area networks

    Author : Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

    Abstract : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. READ MORE

  5. 5. Optimization Models and Methods for Telecommunication Networks using OSPF

    Author : Peter Broström; Michal Pióro; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Telecommunication; OSPF; LP-duality; Polynomial methods; MATHEMATICS; MATEMATIK;

    Abstract : The routing in OSPF Telecommunication networks is determined by computing shortest paths with respect to link weights set by the network operator. All shortest paths to a destination are used by the routers when traffic is routed, and the routers split the traffic evenly when alternative shortest paths exist. READ MORE
