Title
Demo: WARP drive - accelerating wireless multi-hop cross-layer experimentation on SDRs
Abstract
Rapid prototyping of cross-layer multi-hop schemes in wireless networks often poses a hard challenge. While SDRs allow to implement virtually any cross-layer technique, the underlying programming models for rapid prototyping are inherently designed for one-hop communication. Moreover, existing solutions are typically non-real-time and fall back to offline processing. While this is well-suited for evaluating techniques at the physical layer, the media access control and network layers demand interactivity. Further, network size becomes a critical parameter in multi-hop settings but the size of SDR testbeds is often limited, requiring costly reimplementations in a network simulator to investigate larger settings. We develop a framework to overcome these limitations and enable rapid prototyping of cross-layer multi-hop mechanisms on SDRs. We build on (1) a modular software design to allow for mechanism exchange, (2) a virtual timeline to abstract from the non-real-time nature of transmissions, and (3) a seamless switch from practical experiments to simulations using the same code. We provide a reference implementation of our framework to the community as a starting point for rapid prototyping of cross-layer multi-hop mechanisms.
