Cognitive Radio Programming: Existing Solutions and Open Issues
نویسندگان
چکیده
Software defined radio (sdr) technology has evolved rapidly and is now reaching market maturity, providing solutions for cognitive radio applications. Still, a lot of issues have yet to be studied. In this paper, we highlight the constraints imposed by recent radio protocols and we present current architectures and solutions for programming sdr. We also list the challenges to overcome in order to reach mastery of future cognitive radios systems.

Cognitive Radio Programming Survey
Cognitive radio is based on Software Defined Radio (SDR) technology. The commercial success of smart radio applications and cognitive radio networks will be very dependent on cost, performance, and power consumption of SDR hardware platforms. SDR hardware is now available, but many issues have yet to be studied. In this chapter, the authors detail the constraints imposed by recent radio protoco...

متن کاملA Comprehensive Study of Routing Protocols for Cognitive Radio Networks
The rapid development of wireless communication technologies results in the problem of radio spectrum shortage. Additionally, the traditional fixed spectrum allocation scheme can lead to the significant spectrum underutilization. Cognitive radio (CR) is an emerging technology to solve those problems by enabling unlicensed users to opportunistically access the available licensed bands in an inte...
متن کاملRouting Solutions in Cognitive Radio Network Using Local Network State Information
Cognitive Radio (CR) technology is introduced to solve the problem of spectrum usage inefficiency of wireless networks. CR technology allows sharing of licensed spectrum band in opportunistic and non interfering manner. However it should be aware of spectrum availability and Primary User (PU) activities. Routing and spectrum management are the main challenges in Cognitive Radio Network. Here ro...
متن کاملSpectrum sharing methods for the coexistence of multiple RF systems: A survey
Due to the explosive growth of wireless devices and wireless traffic, the spectrum scarcity problem is becoming more urgent in numerous Radio Frequency (RF) systems. At the same time, many studies have shown that spectrum resources allocated to various existing RF systems are largely underutilized. As a potential solution to this spectrum scarcity problem, spectrum sharing among multiple, poten...
