  1. 1. Internet Access and QoS in Ad Hoc Networks

    University dissertation from Faculty of Engineering, LTH at Lund University

    Author : Ali Hamidian; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ad hoc networks; QoS; IEEE 802.11e; MANET; ad hoc routing; distributed resource reservation; Wireless computer communication; IEEE 802.11; ad hoc; mobile ad hoc networks; EDCA; AODV; distributed QoS;

    Abstract : It is likely that the increased popularity of wireless local area networks (WLANs) together with the continuous technological advances in wireless communication, also increase the interest for ad hoc networks. An ad hoc network is a wireless, autonomous, infrastructure-less network composed of stations that communicate with each other directly in a peer-to-peer fashion. READ MORE

  2. 2. Implementation and Experimental Evaluation of Wireless Ad hoc Routing Protocols

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Lundgren; Uppsala universitet.; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wireless ad hoc network; mobile ad hoc network; MANET; experimental evaluation; real world experiments; communication gray zone; gray zone; routing protocol; ad hoc networking; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. New routing protocols that can adapt to the frequent topology changes induced by node mobility and varying link qualities are needed. READ MORE

  3. 3. Identity and Anonymity in Ad Hoc Networks

    University dissertation from Karlstad : Karlstad University

    Author : Leonardo Augusto Martucci; Karlstads universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; privacy; identity; anonymity; pseudonymity; Sybil attack; security; ad hoc; coputer networks; Datavetenskap; Computer Science;

    Abstract : In ad hoc networks every device is responsible for its own basic computer services, including packet routing, data forwarding, security, and privacy. Most of the protocols used in wired networks are not suitable for ad hoc networks, since they were designed for static environments with defined borders and highly specialized devices, such as routers, authentication servers, and firewalls.

  4. 4. AD/HD and autism spectrum disorders in adults

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Björn Hofvander; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Behaviour disorders; Comorbidity; AD HD; Autism spectrum disorders; Outcome;

    Abstract : Background: Attention deficit/hyperactivity disorder (AD/HD) and autism spectrum disorders (ASDs) are early-onset, but often life-time impairing, neurodevelopmental disorders. They are highly overlapping and seem to carry considerable risks of negative outcomes, psychiatrically and psychosocially. READ MORE

  5. 5. Ad hoc routing protocol validation

    University dissertation from Uppsala University

    Author : Oskar Wibling; Uppsala universitet.; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Abstract : We explore and evaluate methods for validation of ad hoc routing protocols which are used to set up forwarding paths in spontaneous networks of mobile devices. The focus is automatic formal verification but we also make an initial account of a protocol performance comparison using structured live testing. READ MORE
