Literature ReviewOpen accessIn the abstractSurvey and Comparison of Operating Concept for Routing Protocols in DTNKawakib K. Ahmed, Mohd Hasbullah Omar, Suhaidi HassanDelay Tolerant Network (DTN) are promising techniques to enable data transmission in challenging scenarios where sophisticated infrastructure is not available and the end-to-end path does not exist at the moment of data transmission. These networks are characterized by a long delay, intermittent connectivity and high error rates. Furthermore, the dynamic topology of the network may change randomly. Therefore, routing is … …Journal of Computer Science, Vol. 12, Issue 3 · 23 Apr 2016 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on OFDM and PAPR Reduction TechniquesArun Kumar, Manisha GuptaOFDM is a multi carrier transmission technique where a single set of data is transmitted over a number of sub-carrier. OFDM takes the advantage of multi-path propagation and reduces the fading effect. The idea of OFDM is to split the total transmission bandwidth into a number of orthogonal subcarriers which reduces the inter-symbol-interference, power consumption and increases the capacity and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 4 Jun 2015 · 8,401 accessesView PDFCite
