With approximately 7 billion cellphone subscriptions around the world, mobility and computing became pervasive in our society and enterprise. additionally, new cellular multimedia verbal exchange companies are demanding telecommunication operators. To aid the numerous bring up in multimedia traffic—especially video—over instant networks, new technological infrastructure has to be created. Cognitive Radio Networks (CRNs) are largely considered as the most promising applied sciences for destiny instant communications. This publication explains easy methods to successfully carry video, audio, and different information over CRNs.
Covering complex algorithms, protocols, and hardware-/software-based experiments, this publication describes tips on how to encode video in a prioritized method to ship to dynamic radio hyperlinks. It discusses varied FEC codes for video reliability and explains how various desktop studying algorithms can be utilized for video quality controls. It additionally explains find out how to use available software program instruments to construct a CRN simulation version.
This publication explains either theoretical and experimental designs. It describes how common software program radio peripheral (USRP) forums can be utilized for real-time, high-resolution video transmission. It additionally discusses how a USRP board can feel the spectrum dynamics and the way it may be managed by way of GNU Radio software program. A separate bankruptcy discusses how the community simulator ns-2 can be utilized to construct a simulated CRN platform.
