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

    Author : Ali Hamidian; Lunds universitet; []
    Keywords : 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

    Author : Henrik Lundgren; Per Gunningberg; Christian Tschudin; Marco Conti; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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; Computer science; 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

    Author : Leonardo Augusto Martucci; Simone Fischer-Hübner; Tuomas Aura; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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 hoc routing protocol validation

    Author : Oskar Wibling; Joachim Parrow; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Radio Network Planning and Resource Optimization : Mathematical Models and Algorithms for UMTS, WLANs, and Ad Hoc Networks

    Author : Iana Siomina; Di Yuan; Peter Värbrand; Arie Koster; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; planning; optimization; wireless networks; radio resources; UMTS; WLAN; ad hoc; Telecommunication; Telekommunikation;

    Abstract : The tremendous popularity of wireless technologies during the last decade has created a considerable expansion of wireless networks both in size and use. This fact, together with a great variety of mobile devices and numerous di®erent services that are becoming increasingly resourcedemanding, have attracted the attention of many researchers into the area of radio resource planning and optimization.
