2. 1. Relaying for Industrial Wireless Networks

   Author : Svetlana Girs; Fredrik Brännström; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

   Abstract : The interest in wireless technology for industrial applications has increased dramatically over the last few years. Wireless communication can reduce cost and complexity, enable mobility and provide much higher flexibility than its wired counterparts. READ MORE

4. 2. On the Performance of Underlay Cognitive Radio Networks with Interference Constraints and Relaying

   Author : Charles Kabiri; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Cognitive Cooperative Relay Networks; Underlay Spectrum Access; Interference Constraint; Outage Constraint;

   Abstract : Efficiently allocating the scarce and expensive radio resources is a key challenge for advanced radio communication systems. To this end, cognitive radio (CR) has emerged as a promising solution which can offer considerable improvements in spectrum utilization. READ MORE

5. 3. Live Streaming in P2P and Hybrid P2P-Cloud Environments for the Open Internet

   Author : Amir H. Payberah; Seif Haridi; Anwitaman Datta; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Peer-to-Peer (P2P) live media streaming is an emerging technology that reduces the barrier to stream live events over the Internet. However, providing a high quality media stream using P2P overlay networks is challenging and gives raise to a number of issues: (i) how to guarantee quality of the service (QoS) in the presence of dynamism, (ii) how to incentivize nodes to participate in media distribution, (iii) how to avoid bottlenecks in the overlay, and (iv) how to deal with nodes that reside behind Network Address Translators gateways (NATs).

7. 5. On the Performance Analysis of Cooperative Communications with Practical Constraints

   Author : Quang Trung Duong; Blekinge Tekniska Högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : With the rapid development of multimedia services, wireless communication engineers may face a major challenge to meet the demand of higher data-rate communication over error-prone mobile radio channels. As a promising solution, the concept of cooperative communication, where a so-called relay node is formed to assist the direct link, has recently been applied to alleviate the severe pathloss and shadowing effects in wireless systems.
