2. 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

4. 2. Identity and Anonymity in Ad Hoc Networks

   Author : Leonardo Augusto Martucci; Simone Fischer-Hübner; Tuomas Aura; Karlstads universitet; []
   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.

5. 3. Implementation and Experimental Evaluation of Wireless Ad hoc Routing Protocols

   Author : Henrik Lundgren; Per Gunningberg; Christian Tschudin; Marco Conti; Uppsala universitet; []
   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; 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

6. 4. 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 : 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.

7. 5. Coping with Misbehavior in Mobile Ad-hoc Networks

   Author : Sonja Buchegger; Jean-Yves Le Boudec; EPFL; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mobile ad-hoc networks; incentives; cooperation; reputation systems; Bayes; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : n this work, we address the question of how to enable a system to operate despite the presence of misbehavior. Specifically, in a mobile ad-hoc network, how can we keep the network functional for normal nodes when other nodes do not route and forward correctly? Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. READ MORE
