  1. 1. Cooperative Communications Link Reliability and Power Efficiency

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Tafzeel ur Rehman Ahsin; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Link Reliability; Power Efficiency; Energy Efficiency; Network Coding; Cooperative Relaying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. READ MORE

  2. 2. Future Technology Support of Command and Control Assessing the impact of assumed future technologies on cooperative command and control

    University dissertation from Uppsala : Uppsala universitet

    Author : Mats Persson; Uppsala universitet.; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; command; control; cooperative; collaboration; decision-making; effectiveness; human-computer interaction; microworld; network-centric; military; team; beslutsfattande; effektivitet; ledning; mikrovärld; militär; människa-datorinteraktion; nätverkscentrerad; samarbete; team; Computer Science with specialization in Human-Computer Interaction; Datavetenskap med inriktning mot människa-datorinteraktion;

    Abstract : In response to technological advances, especially in the field of information and communication technology (ICT), the so called revolution in military affairs (RMA) and later the concept of network-centric warfare (NCW) emerged as a theory to further utilize technology for military command and control (C2). Advocates of the Swedish ROLF 2010-vision and the concept of NCW have made claims and assumptions that future technology will improve mission effectiveness by, for example, increasing the understanding of a current situation and its development, the speed of command, and providing means to utilize more efficient forms of organizations.

    Abstract : Cooperative intelligent transport systems (C-ITS), where vehicles cooperate by exchanging messages wirelessly to avoid, for example, hazardous road traffic situations, receive a great deal of attention throughout the world currently. Many C-ITS applications will utilize the wireless communication technology IEEE 802. READ MORE

  5. 5. Smart Cooperation with Network Coding in Hierarchical Wireless Networks

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Nan Li; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communications; Hierarchical networks; 5G; Cognitive radio; Internet of Things; Cooperative communications; Spectrum sharing; Network coding; Optimization; Performance analysis.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : To achieve more dynamic, efficient and intelligent use of the scarce wireless spectrum resource, the concept of cooperation has been formalized into several hierarchical network models in future mobile networks. Cooperative communications, such as relaying, can potentially increase communication efficiency and spectrum utilization due to the broadcast nature of wireless networks, and may lead to a better support for diverse communication modes with flexible spectrum sharing.
