VoIP for Radio Networks
In the early eighties, a communications protocol was created that allowed the research community to send data anywhere in the world using packet switching networks. This protocol became known as TCP/IP and ultimately resulted in the creation of the revolutionary Internet. TCP/IP actually refers to a suite of different protocols but, at its core, there exists the fundamental protocol commonly re...
متن کاملEfficient radio resource management algorithms in opportunistic cognitive radio networks
Cognitive radio (CR) paradigm was introduced, towards addressing challenges, related with radio spectrum scarcity and increased needs for wireless networking services provision. In this direction, CR networks exploit novel networking architectures, as well as dynamic radio spectrum access techniques and methods, alleviating problems, regarding limited wireless networking resources and their ine...
متن کاملCognitive Radio Network Application Radio
Application of cognitive radios as the wireless terminals in ad hoc networks in emergency situations has distinct advantages. Better bandwidth, interoperability, avoidance of interference, and ant-jamming capabilities are a few such advanta This paper deals with ad hoc networks incorporated with cognitive radios, which acts as wireless terminals, that can be used in emergency situations and can...
متن کاملSpectrum Assignment in Cognitive Radio Networks Using Fuzzy Logic Empowered Ants
The prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. This has motivated researchers to develop cognitive radio (CR) as a smart and dynamic radio access promised solution. A major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. This paper introduces an i...
متن کاملEfficient Utilization of Spectrum in Cognitive Radio Networks
-The main function of the cognitive Radio (CR) is to use spectrum efficiently and accurately. In this paper, the main aim is to use the spectrum efficiently, which has been allocated to different organizations or companies by centralizing the spectrum. This centralization spectrum can also be taken from the companies which are not utilizing the spectrum presently.
