Poster: Realizing All-spectrum Cognitive Networking on a Software-defined Radio Testbed

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.
