  We present the University at Buffalo's Airborne Networking and Communications
Testbed (UB-ANC Drone). UB-ANC Drone is an open software/hardware platform that
aims to facilitate rapid testing and repeatable comparative evaluation of
airborne networking and communications protocols at different layers of the
protocol stack. It combines quadcopters capable of autonomous flight with
sophisticated command and control capabilities and embedded software-defined
radios (SDRs), which enable flexible deployment of novel communications and
networking protocols. This is in contrast to existing airborne network
testbeds, which rely on standard inflexible wireless technologies, e.g., Wi-Fi
or Zigbee. UB-ANC Drone is designed with emphasis on modularity and
extensibility, and is built around popular open-source projects and standards
developed by the research and hobby communities. This makes UB-ANC Drone highly
customizable, while also simplifying its adoption. In this paper, we describe
UB-ANC Drone's hardware and software architecture.
