  2. 1. Wireless Multi Hop Access Networks and Protocols

    Author : Anders Nilsson Plymoth; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi Hop Access; Wireless Networks; Mobile IP; Performance Evaluation; Medium Access Control; Routing; Wireless Ad hoc Networks;

    Abstract : As more and more applications and services in our society now depend on the Internet, it is important that dynamically deployed wireless multi hop networks are able to gain access to the Internet and other infrastructure networks and services. This thesis proposes and evaluates solutions for providing multi hop Internet Access. READ MORE

  4. 2. Extended certificate management system : design and protocols

    Author : Nada Kapidzic Cicovic; KTH; []
    Keywords : ;

    Abstract : This thesis presents an Extended Certificate ManagementSystem (ECMS), a possible solution for a global certificationinfrastructure. The system is based on a combined trust modelthat interconnects different types of security domains, fromindividual users, small organisations to arbitrarily complexorganisations. READ MORE

  5. 3. Human factors and wireless network applications : more bits and better bits

    Author : Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Mark Högskolan Dalarna Ekonomi och samhälle Dougherty; Angela Sasse; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human factors; Mobile multimedia; Access protocols; Computer network performance; Quality of service; Video conferencing; Computer games; Streaming video; Medium access control; Collision detection; Reliable multicast; Computer science; Datavetenskap;

    Abstract : I avhandlingen beskrivs ett hypotetiskt system som kan användas av mobila användare, bland andra taxichaufförer, som exempelvis vill följa en viktig fotbollsmatch. Flera faktorer ställer till problem: Ibland står bilen still och föraren har inget annat att tänka på än matchen. READ MORE

  6. 4. Design and analysis with observational data : Protocols and modeling with the aim of causal inference

    Author : Paulina Jonéus; Mattias Nordin; Per Johansson; Jenny Häggström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; observational studies; protocols guidelines; epidemiology; public health; prostate disease; Statistics; Statistik;

    Abstract : This thesis consists of six papers that study the design and analysis with observational data.There is a growing interest in using real-world evidence (RWE) for regulatory purposes. The belief is that observational data can make drug developmentmore efficient and speed up patient access to new drugs. READ MORE

  7. 5. State-based Channel Access for a Network of Control Systems

    Author : Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Joao Hespanha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; multiple access; event-based; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Wireless networked control systems use shared wireless links to communicate between sensors and controllers, and require a channel access policy to arbitrate access to the links. Existing multiple access protocols perform this role in an agnostic manner, by remaining insular to the applications that run over the network. READ MORE
