3. 2. Performance Analysis of 3-hop using DAF and DF over 2-hop Relaying Protocols

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Faisal Mehmood; Muneeb Ejaz; [2013]
   Keywords : Bit Error Rate; Cognitive Radio; Decode Amplify and Forward; Energy Detection; Probability of Detection; Rayleigh Fading; Relay Network;

   Abstract : In wireless Communication, the need of radio spectrum increases nowadays. But in the system we are losing approximately 82-86% of spectrum most of the time due to the absence of Primary User (PU). To overcome this issue Cognitive Radio (CR) is an admirable approach. READ MORE

6. 5. Assessing the Vulnerability of DTN Data Relaying Schemes to Node Selfishness

   University essay from Institutionen för informationsteknologi

   Author : Shyam Sundar Balasubramanian; [2012]
   Keywords : DTN; selfish nodes; ONE simulator;

   Abstract : The main principle behind the working of delay tolerant networks (DTN) is the mobility of the nodes along with their contact sequences for exchanging data. Nodes which are a part of the DTN network can behave selfishly due to network reservation policy, especially when constrained to energy or storage space. READ MORE
