We present the first complete software-based framework for real-time experimental evaluation of secondary multi-hop cognitive underlay networks with decentralized control. We build a $7$-node software-defined radio testbed and implement a distributed algorithm that maximizes the secondary network throughput, while at the same time avoids interference to primary users through joint Routing and cOde-waveform CHannelization (ROCH). ROCH is implemented using GNU Radio and Universal Software Radio Peripherals ($\mathrm{USRP-N210s}$). The implementation of ROCH is facilitated by the architectural abstractions of a novel radio framework, referred to as RcUBe, that provides reconfigurability at the PHY, MAC, and network layers of the protocol stack.
