  1. 1. Synchronous and Concurrent Transmissions for Consensus in Low-Power Wireless

    Författare :Beshr Al Nahas; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Consesnsus; IoT; IIoT; Capture Effect; Distributed Computing; Wireless Networks; Sensing; TSCH; Bluetooth; Industrial Internet of Things; WSN; Concurrent Transmissions;

    Sammanfattning : With the emergence of the Internet of Things, autonomous vehicles and the Industry 4.0, the need for dependable yet adaptive network protocols is arising. Many of these applications build their operations on distributed consensus. For example, UAVs agree on maneuvers to execute, and industrial systems agree on set-points for actuators. LÄS MER

  5. 5. Cooperative and Cognitive Communication in Wireless Networks

    Författare :Liping Wang; Viktoria Fodor; Anthony Ephremides; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the last decade, significant efforts and progress have been made by both the industry and academia to meet the rapidly growing demand for wireless applications and services. To achieve more flexible, dynamic and intelligent use of the limited wireless spectrum, cooperative transmission and cognitive networking are proposed as two of the key technologies for the next generation wireless communication systems, such as Long-Term Evolution Advanced.
