  2. 1. Cognitive Radio Networks : Elements and Architectures

    Author : Alexandru Popescu; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cognitive radio network management; spectrum access; multiconstrained routing optimization; multi-dimensional adaptation; middleware;

    Abstract : As mobility and computing becomes ever more pervasive in society and business, the non-optimal use of radio resources has created many new challenges for telecommunication operators. Usage patterns of modern wireless handheld devices, such as smartphones and surfboards, have indicated that the signaling traffic generated is many times larger than at a traditional laptop.

    Abstract : Efficiently allocating the scarce and expensive radio resources is a key challenge for advanced radio communication systems. To this end, cognitive radio (CR) has emerged as a promising solution which can offer considerable improvements in spectrum utilization. READ MORE

  6. 4. Transport Analytics Based on Cellular Network Signalling Data

    Author : David Gundlegård; Johan M. Karlsson; Tommy Svensson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Cellular networks of today generate a massive amount of signalling data. A large part of this signalling is generated to handle the mobility of subscribers and contains location information that can be used to fundamentally change our understanding of mobility patterns. READ MORE

  7. 5. Error mitigation in industrial wireless sensor networks : Corrupted packet forensics and recovery

    Author : Filip Barac; Tingting Zhang; Mikael Gidlund; Mário Alves; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Wireless sensor networks (WSN) are gradually penetrating the industrial automation domain. This process is, however, inhibited by a number of challenges that need to be considered and addressed before WSN can serve the most demanding industrial applications. READ MORE
