  1. 21. Optimal Power Control in Cognitive Radio Networks with Fuzzy Logic

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Jhang Shih Yu; [2010]
    Keywords : cognitive radio networks; channel gain; relative distance; fuzzy control; spectrum sharing; path loss; power control; quality of service;

    Abstract : In this thesis, we consider a pair of primary link (PU link) and a pair of cognitive link (CR link) in a fading channel. The PU link and CR link share spectrum simultaneously with different priorities, establishing the spectrum sharing network. The PU link has a higher priority to utilize spectrum with respect to the CR link. READ MORE

    University essay from Institutionen för informationsteknologi

    Author : Benjamin Odiyo; [2010]
    Keywords : ;

    Abstract : Recently there has been a lot of interest in research on performance-challenged networks, which are typically characterized by intermittent connectivity, high mobility, and frequent network partitioning. Attempts to overcome the difficulties in this environment include opportunistic networking and the associated applications that support it. READ MORE

  4. 23. ORWAR: a delay-tolerant protocol implemented on the Android platform

    University essay from RTSLAB - Laboratoriet för realtidssystem

    Author : Davide Anzaldi; [2010]
    Keywords : Delay-tolerant network; DTN; Android; routing protocol; ORWAR; MANET;

    Abstract : The Aim of this thesis is to implement the "Opportunistic DTN Routing with Window-aware Adaptive Replication" (ORWAR) protocol on the Android platform.Delay-Tolerant Networks (DTNs) are particular mobile ad-hoc network (MANET) architectures that try to solve the issues related to the lack of point to point connectivity between the nodes of the network or between its sub-networks (partitions).
