    University essay from KTH/Signalbehandling

    Author : Vanessa Bélec; [2012]
    Keywords : ;

    Abstract : Due to the Internet expansion over the last decades, the pressure for the telecommunications companies to deliver a high performance broadband communication, especially wireless is imminent. Future wireless networks will need to support high data rates in order to meet the requirements of multimedia services. READ MORE

  3. 12. Performance Analysis of Cognitive Radio Network over SIMO System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Iqbal Hasan Haider; MD. Fazla Rabby; [2012]
    Keywords : Cognitive Radio; Outage Probability; Symbol Error Probability; Single Input Multiple Output; Selection Combining; Spectrum Sharing System.;

    Abstract : As resources are limited, radio spectrum becomes congested due to the growth of wireless applications. However, measurements address the fact that most of the licensed spectrums experience low utilization even in intensively teeming areas. READ MORE

  4. 13. On Resilience Challenges in Opportunistic Networks

    University essay from Institutionen för informationsteknologi

    Author : Maria Mehrparvar; [2012]
    Keywords : ;

    Abstract : In opportunistic networks, due to node mobility and sporadic connectivity, disconnection and network partitioning are prevalent. Nonetheless, the network resilience against such sporadic connectivity can be provided through adapting store-carry-and-forward-based  routing protocols which exploit users’ mobility to flow the data in the network even in the absence of end-to-end connectivity.

  6. 15. Performance Analysis and Optimization of One-hop Network Coding in Multi-hop Wireless Networks

    University essay from Institutionen för informationsteknologi

    Author : Lu Liu; [2011]
    Keywords : ;

    Abstract : In this paper, we analyze the performance of one-hop network coding in multi-hop networks and optimize it by two solutions. One is evaluating cost-delay tradeoff of opportunistic network coding in a two-way relay network with asymmetric arrival rates, we first formulate the variance of the queue into a Markov chain and derive the transition probability and the stable distribution.
