ABSTRACT
We implement and real-time demonstrate for the first time ROCH; a distributed cognitive algorithm that maximizes secondary network throughput, while at the same time avoids interference to primary users through joint Routing and cOde-waveform CHannelization. ROCH performance is evaluated on a $7$-node software-defined radio testbed using the open-source radio framework, GNU Radio, and Universal Software Radio Peripherals (USRP-N$210$s). The implementation of ROCH is facilitated by the architectural abstractions of the RcUBe radio framework, that provides real-time reconfigurability at the PHY, MAC, and network layers of the protocol stack.

A software-defined radio based cognitive radio demonstration over FM band
Recent Advances in Wireless Communications and NetworksIn this paper, we present a software-defined radio (SDR) based cognitive radio (CR) implementation and demonstration over the frequency modulation (FM) band. Using GNU Radio as the software platform and USRP (Universal Software Radio Peripheral) SDR ...
Software-defined radio: basics and evolution to cognitive radio
We provide a brief overview over the development of software-defined or reconfigurable radio systems. The need for software-defined radios is underlined and the most important notions used for such reconfigurable transceivers are thoroughly defined. The ...
