1. 1. Distributed Multiple Access and Service Differentiation Algorithms for Wireless Networks

   Författare :Thomas Nilsson; Per-Åke Wedin; Jerry Eriksson; Lennart Bondesson; Andrzej Duda; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

3. 2. Supporting Internet Access and Quality of Service in Distributed Wireless Ad Hoc Networks

   Författare :Ali Hamidian; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoS Guarantees; EDCA; IEEE 802.11e; IEEE 802.11; Mobile Ad Hoc Networks; Wireless Mesh Networks; Internet Access; testbed;

   Sammanfattning : In this era of wireless hysteria, with continuous technological advances in wireless communication and new wireless technologies becoming standardized at a fast rate, we can expect an increased interest for wireless networks, such as ad hoc and mesh networks. These networks operate in a distributed manner, independent of any centralized device. LÄS MER

4. 3. Architectures and Protocols for Performance Improvements of Real-Time Networks

   Författare :Kristina Kunert; Magnus Jonsson; Elisabeth Uhlemann; Eduardo Tovar; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time communication; predictable deadline guarantees; real-time scheduling analysis; timing analysis; admission control; deterministic medium access; MAC; Quality of Service parameters; reliability; redundancy; retransmission scheme; ARQ; truncated ARQ; Automatic Repeat Request; wireless networks; IEEE 802.11; IEEE 802.15.4; fibre-optic networks; AWG; multichannel networks; industrial communications; embedded systems; Computer engineering; Datorteknik;

   Sammanfattning : When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. LÄS MER

5. 4. From Interoperability to Harmonization in Metadata Standardization : Designing an Evolvable Framework for Metadata Harmonization

   Författare :Mikael Nilsson; Ambjörn Naeve; Nils Enlund; Marko Turpeinen; Stuart Sutton; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metadata; dublin core; IEEE LOM; RDF; semantic web; interoperability; standardization; Computer science; Datavetenskap;

   Sammanfattning : Metadata is an increasingly central tool in the current web environment, enabling large-scale, distributed management of resources. Recent years has seen a growth in interaction between previously relatively isolated metadata communities, driven by a need for cross-domain collaboration and exchange. LÄS MER

7. 5. Performance evaluation of safety critical ITS-G5 V2V communications for cooperative driving applications

   Författare :Nikita Lyamin; Alexey Vinel; Magnus Jonsson; Boris Bellalta; Geert Heijenk; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; C-ITS; VANET; ITS-G5; IEEE 802.11p; ETSI; platooning; C-ACC; jamming Denial-of-Service attack; congestion control; cooperative awareness; security in C-ITS;

   Sammanfattning : Intelligent Transport Systems (ITS) are aiming to provide innovative services related to different modes of transport and traffic management, and enable various users to be better informed and make safer, more coordinated and smarter use of transport networks. Cooperative-ITS (C-ITS) support connectivity between vehicles, vehicles and roadside infrastructure, traffic signals as well as with other road users. LÄS MER
