Performance Analysis of Relay Selection Algorithm for Video Transmission in Cooperative Ad Hoc Networks
Radha Raman Chandan, Usha Padma · 2018
The importance of cooperative communication in wireless networks cannot be stressed enough. It has drawn a lot of attention for its capability to successfully tackle the inherent problem of fading in wireless communication. As the world is moving towards precision in all aspects, it is only natural that people desire to watch high quality video for realistic experience. Cooperative communication can undoubtedly help in this regard if appropriate relay selection schemes are used.This paper focusses on two relay selection methods for video transmission. One of the methods is to select the best relay on the basis of channel strength and the other method is to select the best relay based on video awareness. Video is transmitted using QPSK, 16-QAM and 64-QAM modulation schemes. Results showed that the quality of video obtained was better for the relay selection method based on video awareness.
