2. 1. Architectures and Algorithms for Future Wireless Local Area Networks

   Author : Peter Dely; Andreas Kassler; Vasilios Siris; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; WLAN; IEEE 802.11; network management; software defined networking; OpenFlow; optimization; handover; mobility; Computer Science; Datavetenskap;

   Abstract : Future Wireless Local Area Networks (WLANs) with high carrier frequencies and wide channels need a dense deployment of Access Points (APs) to provide good performance. In densely deployed WLANs associations of stations and handovers need to be managed more intelligently than today. READ MORE

4. 2. Distributed Multiple Access and Service Differentiation Algorithms for Wireless Networks

   Author : Thomas Nilsson; Per-Åke Wedin; Jerry Eriksson; Lennart Bondesson; Andrzej Duda; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Local Area Networks; Medium Access Control; Quality of Service; Resource Allocation; IEEE 802.11; IEEE 802.11e; Datatransmission; Datatransmission;

   Abstract : Communicating over a wireless channel poses many unique challenges not found in wired communication because of the special characteristics of the wireless channel. The capacity in a wireless network is typically scarce as a result of the limited bandwidth and many distinct phenomenons, like attenuation and interference, that work destructively on the received signals.

5. 3. Securing Communication in IP-Connected Industrial Wireless Sensor Networks

   Author : Shahid Raza; Mats Björkman; Ben Smeets; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wireless Sensor Networks; Security; 6LoWPAN; IPsec; WirelessHART; Computer science; Datavetenskap; Computer Science; datavetenskap;

   Abstract : With the advent of wireless sensor networks (WSN) and success of wirelesscommunication in the local and personal area networks such asWi-Fi and Bluetoothmore serious efforts to apply standard wireless communication in sensitiveindustrial networks were initiated. This effort resulted in the standardizationof WirelessHART. READ MORE

6. 4. Tracking Area Planning in Cellular Networks : Optimization and Performance Evaluation

   Author : Sara Modarres Razavi; Di Yuan; Calin Curescu; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The enormous competition in the telecommunications market results in the necessity of optimized and cost-efficient networks for the operators and service providers. Tracing users cost-efficiently is one of the major challenges in the study of location management of wireless cellular  networks. READ MORE

7. 5. 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
