A Comparative Study of Software Defined Radio and Cognitive Radio Network Technology Security
نویسنده
چکیده
Software Defined Radio (SDR) and Cognitive Radio (CR) are fast technologies, which can be used to reduce the spectrum shortage problem. The modern software defined radio has been called the heart of a cognitive radio. The applications executing on the radio differentiate a cognitive radio from a software-defined radio. Additional hardware in the form of sensors and actuators increases the more cognitive radio applications. Cognitive radio networks have been become an increasingly part of the wireless networking landscape due to the increasing scarcity of spectrum resources. A number of wireless applications have been developing over the last decade. Government agencies give the license to most of the frequency spectrum, such as Federal Communications Commission (FCC). The main objective of this paper is to analyze the SDR based Cognitive radio, threats and security issue of the main recent advancements and architectures of Software Defined Radio and cognitive radio networks. Keywords— Software Defined Radio (SDR), Cognitive Radio (CR), Threats, Protections.
