1. 6. Traffic Modeling and Evaluation of QoSschemes in Wide Area MonitoringSystem

   Master-uppsats, KTH/Industriella informations- och styrsystem

   Författare :Björn Johanson; [2013]
   Nyckelord :;

   Sammanfattning : To prevent a power grid from having disturbances that may, in a worst case scenario, blackout entire countries, Transmission System Operators (TSO) want to be able to see what happens in different parts of the network faster, to have time to do the necessary changes and regulate the power grid. For this reason, a new technology called PMU-based Wide Area Monitoring System (WAMS) has been introduced to allow the real-time monitoring of the power grid. LÄS MER

3. 7. Implementation Of Wireless Channel Propagation Models In OPNET

   Master-uppsats, Avdelningen för informations- och kommunikationssystem

   Författare :Zhijuan Guo; [2013]
   Nyckelord :OPNET; channel model; power fading; WSN;

   Sammanfattning : In recent times, there has been a significant amount of research regarding the physical layer of wireless communications . The part of the physical layer, which cannot be ignored, is channel propagation. Different environments have different channels. LÄS MER

4. 8. Priority-based THVRG in Industrial Wireless Sensor Network

   Master-uppsats, Institutionen för informationsteknologi och medier

   Författare :Hao Chen; [2013]
   Nyckelord :Industrial Wireless sensor networks; priority; routing algorithms;

   Sammanfattning : With the constant expansion of the industrial monitoring system, there is an urgent requirement to reduce investment and operating costs for the development of industrial communication technology. For industrial real-time monitoring systems, wireless technology can be used in a practical industrial production to take advantages of its flexibility and robustness. LÄS MER
