Research and Analysis on Cognitive Radio Network Security
This paper firstly gives a detail analysis on the security problems faced in cognitive radio network, and introduces the basic issues about cognitive radio network. Then, according to the differences between cognitive radio network and existing wireless network, it analyses and discusses the dynamic spectrum access security and artificial intelligence. Finally, it draws a conclusion to security...
متن کاملCognitive Radio Network: Security Enhancements
Reference to the latest developments the spectrum shortage problems are because of the wireless communication. For the future networks the most practical, scientific and systematic challenges is the use of licensed or unlicensed wireless networks with opportunistic use of the spectrum with, without and limited rules. Since different wireless networks are using different frequency bands. So ther...
متن کاملSecurity in Cognitive Radio Networks Security in Cognitive Radio Networks
While bringing the potential for solving the spectrum underutilization problem using methods such as dynamic and opportunistic spectrum access, Cognitive Radios (CRs) also bring a set of security issues and potential breaches that have to be addressed. These issues come out mainly from the two important capabilities implemented within CRs: their cognition ability and reconfigurability. This cha...
متن کاملReview on Cognitive Radio Network
As the increased demands of wireless channel, there is the need for the proper utilization of the spectrum which leads us to the new technique called cognitive radio technologies. Static spectrum allocation need to merge with a technique where it can be share for the proper utilization of the spectrum. Higher capacity requirement is of great need. As long as the technology is been evolving the ...
متن کاملA layered approach to cognitive radio network security: A survey
Cognitive radios have been identified as a solution to the crowded spectrum issue. With the realization of cognitive radio networks came the recognition that both new and old security threats are relevant. The cognitive radio network is still vulnerable to many of the denial of service, wormhole, routing, and jamming attacks that plague other wireless technologies. In addition, the cognitive ra...
