Future military operations will involve autonomous platforms and systems. In order for these systems to fully achieve their potential, the autonomous platforms need to collaborate. Each platform might have its own independent role in the autonomous system, but they will all work together to reach the same common goal. Hence, an efficient military autonomous system will be highly dependent on a communication network where traffic control is required to better utilize the resources. Through traffic control, the network can discriminate between several levels of importance, routing traffic along different performing network paths. Our motivation for this work was to gain experience with Software Defined Networking (SDN) as a tool for designing and experimenting with new network functionality in an environment where the radios are developed for operational use. Our objective was to gain experience by running SDN along with traditional routing in a heterogeneous network consisting of autonomous platforms. SDN was used as a tool to employ traffic control, so that we could intercept and further traffic engineer-specific traffic along with ordinary routing. Different traffic types were forwarded dependent on the capabilities of the radio networks. Our testbed consisted of different autonomous platforms, i.e. Unmanned Aerial Vehicle (UAV), Unmanned Ground Vehicle (UGV), and Unattended Ground Sensor (UGS). An experiment with the testbed was performed at Rygge Aerodrome where most elements of the testbed were tested, except physical elevation of the UAV platform. Through the experiment, several challenges were identified. In collaboration …
